Team GB pair face badminton rematch at Olympics
Great Britain's Chris Adcock and Imogen Bankier will face the Chinese pair they lost to at last year's World Championships in the group stages of the London 2012 Olympics.
But after losing at Wembley Arena last year, the Anglo-Scots pair have improved their record against Zhang Nan and Zhao Yunlei, winning two of their last three meetings.
"Obviously they're the top seeds, but we've shown that we've beaten them twice in the last three times, so I definitely believe we can win," said Adcock.
"I kind of expected getting the number one Chinese pair as we've played them so often this year and it was the thought that it was always going to happen.
"We've also got two good European pairs with the German pair and the Russian pair. The key thing is that we if play well on the day, we can win.
"The thing with all the pairs is that if we don't have a good day, we'll lose. So the onus is on ourselves and hopefully if we can play well, we can progress through.
"It's a 50/50 game and I suspect we're one pair the Chinese didn't want to face in their group so I think we can take that forward.
"We learnt a lot the last time we played them so hopefully we can use that again."
If both pairs progress out of the group stage, they are not due to meet again until the final, while Group A also sees the 12th seeds face Alexandr Nikolaenko and Valeri Sorokina of Russia and world number 16 pair, Germany's Michael Fuchs and Birgit Michels.
In the men's singles, Rajiv Ouseph, seeded 15th, faces Henri Hurskainen, the world No 43 from Sweden who reached the finals of the European Championships in April, while world number 29 Kevin Corden, from Guatemala, completes the line-up in his group.
If Ouseph tops his group, he is likely to face Japan's sixth seed, Sho Sasaki.
Susan Egelstaff, Team GB's sole women's singles representative and the world number 36, also faces a tricky draw.
The 28-year-old Glaswegian faces 12th seed Sayaka Sato of Japan and world No 87 Maja Tvrdy of Slovenia, with only the top spot qualifying to the last 16.
If Egelstaff progresses from her group, she is expected to face Tine Baun, the former Denmark number one, in the knockout stages.
