Rafael Nadal (Spain)

Age 24.

World ranking 1.

Grand Slam best Won French Open (2005, 2006, 2007, 2008, 2010), Wimbledon (2008, 2010), Australian Open (2009), US Open (2010)

World Tour Finals best Semi-finals (2006, 2007)

Aiming to become only second man (after Andre Agassi) to win all four Grand Slam titles, Olympic gold, Davis Cup and end-of-year championships. However, his year seems to have taken its toll in recent weeks.

Roger Federer (Switzerland)

Age 29.

World ranking 2.

Grand Slam best Won Wimbledon (2003, 2004, 2005, 2006, 2007, 2009), Australian Open (2004, 2006, 2007, 2010), US Open (2004, 2005, 2006, 2007, 2008), French Open (2009)

World Tour Finals best Winner (2003, 04, 06, 07)

Recently dropped out of top two in world rankings for first time in seven years. On his day still the best on quicker surfaces but struggles to maintain consistency.

Novak Djokovic (Serbia)

Age 23.

World ranking 3.

Grand Slam best Won Australian Open (2008)

World Tour Finals best Winner (2008)

Reached first Grand Slam final for two and a half years at US Open two months ago, losing to Nadal. Playing in Serbia's first Davis Cup final against France in a fortnight's time may be a bigger priority than London.

Robin Soderling (Sweden)

Age 26.

World ranking 4.

Grand Slam best French Open runner-up (2009, 2010)

World Tour Finals best Semi-finals (2009)

Transformed from journeyman pro into major contender after beating Nadal in the quarter-finals of last year's French Open. Overtook Murray in rankings by winning first Masters Series title in Paris last weekend.

Andy Murray (Britain)

Age 23.

World ranking 5.

Grand Slam best Runner-up at US Open (2008) and Australian Open (2010)

World Tour Finals best Semi-finals (2008)

Hit form of his life to reach Australian Open final in January but has had up-and-down year. Has won two Masters Series titles since splitting with his coach, Miles Maclagan, who has yet to be replaced.

Tomas Berdych (Czech Republic)

Age 25.

World ranking 6.

Grand Slam best Wimbledon runner-up (2010)

World Tour Finals best First appearance

Big hitter who has finally started to realise his potential, knocking out Federer at Wimbledon, though he has gone off the boil since defeat in the final there to Nadal, losing in the first round of the US Open to Michael Llodra.

David Ferrer (Spain)

Age 28.

World ranking 7.

Grand Slam best US Open semi-finals (2007)

World Tour Finals best Runner-up (2007)

Consistent performer who has not been out of the world's top 25 for five years but lacks the weapons to win the biggest prizes. Disappointing year in the Slams – going out in the second round in Melbourne and the third at Roland Garros.

Andy Roddick (US)

Age 28.

World ranking 8.

Grand Slam best US Open winner (2003)

World Tour Finals best Semi-finals (2003, 2004, 2007)

Has qualified for finals for eighth year in succession (which only Federer of the current players can beat) but has had a difficult, injury-disrupted year. In September made a disappointing second-round exit at Flushing Meadows.
