Olympics 2012: What to Watch Tonight, Saturday 4 August

Athletics: Men’s 400m Hurdles Semi-finals

7:00pm BBC1, BBC Olympics 1

Britain’s Dai Greene is the current world champion so you’d assume he is the favourite, but it’s not as easy as that. He will have three very good Americans to compete against, and I suspect to win gold Dai will need to run three, four or five tenths faster than ever. Which is not impossible.

You can get an extra boost because you’re at home. What matters most is that he goes there with a clear head. He mustn’t get involved in the trash talk. There’s been a lot going on across the Atlantic, and that tells me the Americans and the Cubans are worried! Kriss Akabusi

Men's football quarter-final: Great Britain v South Korea

7:30pm BBC3, BBC Olympics 8

Having topped their group, Stuart Pearce's men face a South Korean team who have drawn 0-0 in two of their three matches at London 2012. Described by Pearce as a well-prepared and workmanlike side, South Korea will try to frustrate the hosts, for whom goldrush fever is starting to take hold. Patience and perhaps a flash or two of Premier League flair at the Millennium Stadium should see GB through to the semi-final, where their likely opponents would be strong tournament favourites Brazil.

Men’s Long Jump Final

7:55pm BBC1, BBC Olympics 11

It’s quite a modest field in the long jump at the moment. America’s Dwight Phillips, the world champion, is out injured, and another of the best in the field, Panamanian Irving Saladino, hasn’t jumped this year at all. As a result, this event is wide open.

Team GB has this year’s joint world leader, Greg Rutherford, who has had a very solid season. If he hits the board and goes over 8.40m he could well win it.

Chris Tomlinson has jumped poorly this year, struggling to get out to 8m until the London Grand Prix. He’ll need a real turnaround in form to challenge for a medal. Jonathan Edwards

Women’s 100m Final

9:55pm BBC1, BBC Olympics 1

It’s another battle between Jamaica and the USA. Shelly-Ann Fraser-Pryce, 25, is the female Usain Bolt — a phenomenal 100m and 200m runner and the current Olympic champion - while America boasts Allyson Felix.

In the US trials Felix and Jeneba Tarmoh finished in a dead heat for third spot and were due to run a race-off. But incredibly, Tarmoh declined, which gave Felix the chance to go head to head with team-mate Carmelita Jeter.

Don’t rule out Trinidad and Tobago’s Kelly-Ann Baptiste. Darren Campbell
