Born: January 31, 1986 in Shaanxi (Qin) and April 17, 1979 in Shandong (Wang) Entry: 3m synchronised springboard Credentials: Gold at 2007 world championships Why they'll win: Because they have dominated since winning the world championships in 2007. Qin Kai is from Shaanxi, the same province as retired poster boy Tian Liang. While Tian loved the limelight so much it cost him his place, Qin is the ultimate mainland sporting machine. Don't expect juicy quotes or late-night antics - just perfect dives, time after time after time. Veteran Wang Feng is Qin's antithesis, an infectious personality who'll never duck a tough question and speaks with the eloquence of a diplomat. In the synchronised event, China has a depth of talent and training structure unmatched by any other country. They undergo a year-round, military-style training regime, living and training together almost constantly, compared with the several months a year divers in Western countries spend. Added to this is the diving team's ability to hold Wang back from individual events to focus on the team, unthinkable for such a talent in any other team. Of course, this isn't foolproof. In Athens, Peng Bo and Wang Kenan were leading comfortably going into the final round before Wang slipped and fell back-first into the pool. Judges declared the dive void, handing gold to the unheralded Greek duo of Nikolaos Siranidis and Thomas Bimis. It'll take something as dramatic - and heartbreaking - to stop Qin and Wang. Who can stop them: Yuri Kunakov and Dmitri Sautin (Russia), Andreas Wels and Tobias Schellenberg (Germany), Luis Huerta and Yahel Castillo (Mexico). Final: Wednesday, August 13th
