Last-gasp Montpellier go top
Montpellier climbed to the top of Ligue 1 on Saturday when they defeated St Etienne 1-0 at home thanks to a superb late Olivier Giroud goal.
Unheralded Montpellier, who have never won the French title and were not expected to mount a challenge this term, created lots of chances but lacked a cutting edge before league top scorer Giroud struck for the 18th time in Ligue 1 this season.
"There is not much to say. A team attacked and the other only defended," coach Rene Girard told Foot+ television.
Nice's Fabian Monzon scored from the penalty spot after 76 minutes to cancel out Andre Ayew's opener in the 56th minute.

"We stopped the bleeding. We managed a draw under difficult circumstances," coach Didier Deschamps told a news conference.
"We showed heart, courage and fighting spirit."
Hazard put the champions ahead on 36 minutes after he was fouled in the box. Dimitri Payet doubled their lead in the 55th minute after a Hazard pass and Benoit Pedretti completed the victory 12 minutes later.
