Wow. What a match. All about the epics these two, but can Nole go on and win it? And will Murray get out of the group? If he does he'd probably face Federer next. All massive matches. Let me know what you think on Twitter @Reda_Eurosport. Cheers and see you for Berdych-Tsonga later, around 7.45pm.
MURRAY 6-4 3-6 5-7 - GAME SET AND MATCH DJOKOVIC! Match point Djokovic as Murray's backhand return drops long, and he takes it as Murray pumps a poor backhand drive long. A weak way to end a cracking match, Djokovic takes charge of the group with a stunning win while Murray must beat Tsonga.
MURRAY 6-4 3-6 5-6 - Djokovic serving for the match, a big smash setting him on his way. Then a baseline battle, and it's Djokovic's turn to go long. And Nole nets a two-hander on the run, and it swings in Murray's favour! And two break-back points as Murray smashes clear of Nole after the Serb clipped net! Incredible!! The first is saved as Nole smashes clear - mighty serve that Murray nets for deuce.
MURRAY 6-4 3-6 5-6 - BREAK! Murray is finding his winners again but Djokovic levels with a couple of smashes, the second beyond the Scot. Too close to call again between these two. Some dufus yells out and gets a death-stare from Murray, who nets his next follow-up. Annoying, chuck him out. And his next drive lands long for two break points!! Deary me. First is saved with an ace down the middle, his ninth. But he goes long on the next follow-up and it's a break!!
MURRAY 6-4 3-6 5-5 - First point to Nole as a Murray winner lands just long, he was stranded too! Level as a super crosscourt pass from Murray leaves Nole for dead. Horribly long first serve now for Djokovic and the next rally sees him go long! 15-30 in Murray's favour! But level as Murray almost meets a Nole drop shot but, staggering, sends it long. And a cracking volley at the net brings up game point Nole, taken as Murray spins a forehand wide.
MURRAY 6-4 3-6 5-4 - Murray drops a point to 15-15 as a backhand strikes net and lands wide. And a monster return catches him off guard, backhanding wide, and now Nole has a sniff!! But Murray sets up a rush to net on shot three, which he passes clear with a cool volley. Now Djoko hits long and Murray has hold point - first serve is wide... second isn't great but Nole's second forehand lands wide. Djokovic suddenly serving to stay in the match!!
MURRAY 6-4 3-6 4-4 - BREAK! HawkEye comes good for Murray as it shows Nole went wide! It looked wide and Murray is right back in it! Stunning!!
MURRAY 6-4 3-6 3-4 - First blood to Djokovic on serve but he goes long next and it's level. Murray works the backhand before cracking a vicious forehand winner that Nole meets but with a mis-hit long! 15-30. Half a chance Murray, but an ACE. Challenged... WIDE! Overruled, second serve. A millimetre in that. And two break points as a thrilling rally sees Nole crack first to go long! The first is saved as Murray hits wide, he's angry with himself. Now Nole goes wide, Murray challenges....
The stats are very even - Murray with 8 aces to Nole's 4 but the Serb winning fractionally more points off serve, and getting fractionally more first serves in. All about the key points it seems.
Stones. Better. Can Murray break back or has Nole got his number? Tweet me @Reda_Eurosport with your predictions.
MURRAY 6-4 3-6 3-4 - Successful Murray hustle to net sees Djokovic flick long for game ppint, which is taken as a forehand bullet forces Nole long with his backhand. Another tough hold of the Murray serve.
MURRAY 6-4 3-6 2-4 - Just shy of two hours now as Murray nets a forehand drive from deep. He's not playing well now, having done so well in the first set. Nole then pumps an attempted winner long, Murray stranded too so an escape there. ACE. (Applause). A fantastic point sees Nole level to 30 after some flashing strikes from all angles across the baseline, and break point as Murray nets a forehand! Saved as Nole nets off second serve. Deuce.
MURRAY 6-4 3-6 2-4 - Murray somehow stays alive after a Nole smash, with the Serb slipping his next forehand wide for 15-15. Murray then flicks what could have been a super winner, but it goes long. Shame. Then more bad luck as a wicked return lands a centimetre wide. And Djokovic holds to 15 as his diagonal backhand is spun long by Murray.
MURRAY 6-4 3-6 2-3 - Advantage Murray once more as he meets Nole's flicked return with interest, and finally he holds after contstructing the point to set up an approach shot passed to the left. Massive hold but he needs to break back!
MURRAY 6-4 3-6 1-3 - Now it's another break point as a weak Nole return is met with a weaker backhand to net. "Come on Murray" yells one of his fellow Scots to my rear and it seems to help as Nole goes long after a thrilling baseline exchange! Massive serve down the middle for game point, but the next point sees him land one long. Another counterpunching rally resumes with Nole netting his backhand, but he flicks a super drive wide of Murray for deuce again.
MURRAY 6-4 3-6 1-3 - Murray with a weak mis-hit wide off his first service point here. He needs to stop the rot, his shoulders are dropping a touch. And he nets under no pressure while trying to pass a stranded Djokovic for 0-30, although he pulls one back with a smash that a sliding Nole can only backhand to net. Nole pumps a winner down the line wide, he challenges - call stands. 30-30. Fine winner from Murray into space on the right, and he should hold but drop-volleys to net with Nole prone!
MURRAY 6-4 3-6 1-3 - Murray dominates the opening rally on Nole's serve as he crushes away a forehand winner after it dropped to him off the net. But a weak forehand of his own hits string and it's 15-15. Then he returns long off second serve. A widening rally again favours Nole as Murray nets, and Nole holds with a forehand winner off the right side of the baseline. Murray challenges but it was in.
MURRAY 6-4 3-6 1-2 - BREAK! Nole edges ahead on the Murray serve and Murray then goes long for 0-30! And now three break points as again Murray swings one long from deep! The architect of his own downfall here! He almost double faults away the break but just keeps it in, and wins the next point as Nole nets a backhand. But Murray goes long again with his follow-up backhand and Djokovic has taken charge of the match!
MURRAY 6-4 3-6 1-1 - A backhand exchange sees Nole go long but a good challenge sees it overturned, clipped white for sure. Point replayed at 15-0, but Murray wins it as he stands up a return that an off-kilter Nole spins wide. He makes up for it with a smash well beyond Murray, while the next point - which Murray had dictated - goes to Nole as the Scot pumps one long. Poor, as he had him on the run. Nole holds with a cool forehand that almost forces a magic Murray winner that drops just wide.
MURRAY 6-4 3-6 1-0 - Final set, Murray to serve initially. ACE. Promising start. ACE again, but Djokovic challenges - yes. Nole returns several yards long now, and does so again, and Murray holds to love as Nole repeats the trick.
Ha, hot on the heels of Noel, brother Liam now 'entertains' the crowd as they changeover. This is too tight to call, Murray played the better tennis initially but Nole is resurgent and Muzzah is getting sloppy. Who do you reckon will take this now? Tell me on Twitter @Reda_Eurosport.
MURRAY 6-4 3-6 - SET! Good start for Djokovic as his first serve of this game is returned well long. Murray then cracks a forehand cross to net, and it's 40-0 as Murray flicks a backhand just wide after Nole somehow stayed alive following a flashing return that had him stretching. Unreturnable serve and Nole holds to love to take the second set. All the way again!!
MURRAY 6-4 3-5 - Lovely winner down the line from Nole but it's 30-15 on Murray's serve, and an ACE brings up game point. Taken as a Nole backhand volley drifts beyond the baseline, meaning Djokovic must serve to force a decider.
Robin - they call him "Nole" because that is his nickname. No-one in Serbia calls him "Djoko" or "Djoker", that's an Anglophone thing. It's kind of like Olivers being called Ollie. Standard abbreviation.
MURRAY 6-4 2-5 - Murray is made of stern stuff though and puts a fabulous pass beyond the approaching Nole for 0-15. A wild Murray backhand goes long for 15-15, before a cagey backhand exchange again sees Murray land wide. Cracking serve for 40-15 and Djokovic defends the break as Murray returns wide.
MURRAY 6-4 2-4 – BREAK! Murray rides an unconvincing first point to this game as Nole nets his next forehand. The Serb returns long after a cracking serve out wide, but level again as Murray's fourth real error today sees him net a forehand cross. And now break point as Nole shades a thrilling rally with a pair of volleys at the net! Sloppy from Murray, who has underhit a few this game - and he goes long terribly with his volley! Challenged... just out. Djokovic breaks!
Bit of Noel Gallagher at the changeover. Which way do you reckon this will go? Murray with the better chances to break so far in the second, but Nole is a monumental fighter... Let me know on Twitter @Reda_Eurosport.
MURRAY 6-4 2-3 – Murray does really well to reach a Nole drop but he flicks it wide. Then Nole pushes to net before cushioning a volley wide of Murray. ACE. And a love hold as Murray spins a forehand return long.
MURRAY 6-4 2-2 – Murray wants to get right back on to Nole’s serve again, a treat of a forehand fizzing past the Serb. Then Murray goes long from a cagey rally by both men, but Nole goes wide with a crosscourter. He challenges… call stands, he was wide. And Murray holds to 15 as Nole returns his second serve long.
MURRAY 6-4 1-2 - Finally Nole has advantage as Murray puts one long, the Briton then netting a backhand to allow the Serb to claim an important hold.
MURRAY 6-4 1-1 - Nole's next service game sees him flick it long. But a long rally - in both senses of the word - sees Murray spin a backhand wide. The Brit does really well to stay alive in the next point before digging out a super forehand into the corner that Nole nets. 15-30 but rubbed out with an angled serve returned to net. Another great rally sees Nole crack first, clipping the net to land wide. Break point Murray! Deuce as Murray's challenge ona Nole winner is overruled.
MURRAY 6-4 1-1 - Fabulous winner from Murray, opening up his forehand off the line. But his second real unforced error today levels, a weak backhand to net. Less of that please. Murray bosses the next point though as Nole goes long, with the Serb pumping a double-handed backhand wide, accompanied by a howl of frustration. But he rules the next point as Murray weakly nets on the move, 40-30, but he holds with an ACE, his fifth today I make that.
MURRAY 6-4 0-1 - Love hold for Nole to start the second set, the Serb already looking more aggressive as Murray volleys long after some powerful drives.
MURRAY 6-4 - SET! Super pass again from Murray as he hustles to net from deep. Murray is taking it to Nole, much more comfortable on the front foot these days. Then a marvellous drop shot is met by an incredible Nole lunge, only for his drop to land the wrong side of the line via the net. Unlucky Nole! 30-0, and Murray challenges as he goes long after a longish Nole drive - great call, twas indeed long. 40-0, three set points, and Murray takes them as Nole goes long! Clinial from Muzzard.
Another one of these MTV style changeovers as the music returns to atrocious candy pop from the West Coast of the USA. They should get McEnroe on the decks. Murray now to serve for the set...
MURRAY 5-4 – Finally Djokovic holds, a monster game in the end, with Murray sliding one into net after a brief but swashbuckling rally from both men. Only worthy if Nole breaks back now as Murray is serving for the set!
MURRAY 5-3 – Murray exploits an underhit smash and drop shot combination to flick a delightful drop of his own just over the net. Break and set point Murray! But a scooped forehand on the run goes long, Murray's first real error, and it's back to deuce. And game point Nole with a fine forehand that dips off the line. A super Murray return is somehow kept in play by Nole but the Scot controls the point and Nole nets. Deuce again. Murray gets a lucky one off the net but then slices wide...
MURRAY 5-3 – Nole finds the lines with some nice clipped forehands before rushing to net and backhand volleying away. Murray spins an attempted backhand winner just long, while Nole challenges a first-serve ace called wide - good shout Nole, twas good! 40-0. Off second serve Murray bosses the next point, his power and depth too much for Nole who nets, with Muzzah repeating the trick for 40-30. And now deuce as Nole pumps long from Murray's weakish return. Poor.
MURRAY 5-3 – Murray misses a backhand cross on his first service point here. The crowd get nervous, apart from the smattering of Serbs and Macedonians yelling Nole's name between points. Then Djoko hits long, before Murray builds a superb point that sets up a diagonal forehand winner down the right. Classy. But a backhand slice lands inches wide and it's 30-30. ACE down the middle. 135 mph that. And Muzzah holds as Nole backhand returns long off second serve. Nole serving to stay in the set.
MURRAY 4-3 – Nole 'does a Murray' by dictating the tempo of the opening point from deep as the world no.3 goes long. But a rotten mis-hit from the Serb after he caught Murray off balance sees them level at 15. A repeat of the opening point ultimately sees Nole pass Murray for the lead, and Murray goes long in search of a forehand winner down the line. Nole goes long after a super Murray return builds the point in his favour, but Nole holds as a crosscourter from Murray misses.
MURRAY 4-2 – ACE starts this next Murray service game. And a kick serve out wide leaves Nole stumbling for 30, and another that he returns long. Three 130mph+ serves in a row. The next is long though, and we have the first double fault as Murray misses the middle. 40-15. The umpire then has to call fault on a first serve clearly wide, everyone else asleep, but Murray holds off a cagey second serve as he bosses the baseline while Nole clips net to go wide.
MURRAY 3-2 –Murray fails to test Nole with the forehands from deep, but pulls one back with a cool pass into his favoured left side. Murray nets off the next rally but he seems confident enough to defend his serve though and is happy to get back on to it.
MURRAY 3-1 - After a wide first serve Murray clips the net. As a result his next delivery is tentative, but Nole goes long anyway. 30-0. Another solid hold as Nole returns long for 40-0, and Murray passes him with a dipping forehand for the love game.
First change of the day. The music somewhat less offensive than previous days, some mild house to keep things ticking. Great start for Murray, who looks keener and sharper than on Monday. Any comments, you know where to find me @Reda_Eurosport on Twitter.
MURRAY 2-1 – An unreturnable serve from Nole, then a near winner from Murray clips the net and lands his side. Next return lands long, but Djokovic goes wide to drop a point to 40-15. Murray spins a forehand wide off the next rally and Nole gets off the board.
MURRAY 2-0 - Nole's first return today is wide, and his second makes Murray work. Great stuff from the baseline from both men and, with Nole seemingly having Murray on the back foot, the Scot again rushes the net and passes the Serb. Glorious shot for 30. ACE! 40-0. And off second serve Nole nets and it's a love hold to back the break.
MURRAY 1-0 - BREAK! A teasing rally to start sees Nole go long. But Murray's next return skips into the net... Off second serve now and Murray finds some fantastic length on the baseline rally as Nole eventually hits long. 15-30. But a weak backhand to net concedes the lead. Nole then nets after Murray finds length off his second serve and it's break point Murray! And he takes it with a fabulous point from deep before rushing to net and passing Nole, who thought he'd won it with the drop! Super!
So, just shy of 2pm dead, this battle commences. Djokovic serves to start after Murray won the toss.
Nice World Tour Finals stats from our mates at Infostrada: In 5 previous appearances at the ATPWorldTour Finals, Novak Djokovic has won his first 2 matches only once (2008, when he won the title). Andy Murray has only won both his first two matches once (out of four previous appearances) – also in 2008.
Massive cheer for Murray as he comes out. Remember, you can interact with me about this match or these Finals in general by Tweeting on @Reda_Eurosport. The players are only just set to come out on court so expect a 2pm start.
PERMUTATIONS: If Djokovic wins in straight sets, he is through on account of having beaten Tsonga in straight sets. If Murray wins he is on the brink but will have to at least take a set off Tsonga in the final group clash, because he dropped a set against Berdych.
Good news for fans of this event being at the magnificent O2 Arena in London - the ATP announced today that the World Tour Finals will be held here until at least 2015. Whoop. Fantastic venue for tennis, almost like a boxing arena in scale and tone, really pushing the combat theme to the fore.
The doubles are done so this match should get underway close to schedule, which is nominally set at 1.45pm UK time but has mostly been later than 2pm.
HEAD TO HEAD: Currently it stands at 9-7 to Djokovic, but Murray has got the better of Djokovic in recent times, most notably at the Olympics and the US Open final. But Nole won their last clash at the final of the Shanghai Masters, which was itself a mini-opus fitting of what is shaping up to be one of the all-time great rivalries.
I’m Reda Maher and I’ll be commentating for you today from the O2 in North Greenwich. If you have any predictions on this friendly grudge match, ping them my way on Twitter @Reda_Eurosport.
Hello and welcome to our LIVE coverage of what promises to be another classic in the ongoing rivalry between US Open champion Andy Murray and world number one Novak Djokovic. It’s scheduled to start at 1.45pm UK time, dependent on the prior doubles match at the O2.
