Swimming: Men’s 4 x 100m Freestyle Relay
8.54pm, BBC1, BBC Olympics 6
This is normally a blue riband event for the Americans, but they go into this as underdogs. Yes, the US have both Ryan Lochte and Michael Phelps, but they’re not the top two in the world at 100m freestyle — they’re better at 200m. The Australians are the favourites, and there are three Russians in this year’s 100m top ten, too. This is one of the events that might affect how many golds Phelps can win. The Americans don’t have the same strength in depth as they did in Beijing. Sharron Davies
