The ATP World Tour Finals, played at the end of each season, sees the top eight players in the world rankings compete against each other for a purse of over $5million. The players are split into two groups of four, with the best two players from each group advancing to the semi-finals, from where a normal knock-out format commences. The venue was moved to London's 02 Arena from 2009 - the first tournament in the English capital was won by Nikolay Davydenko.

ATP Odds

The tournament provides the biggest ATP betting market of the season outside the majors and is normally dominated by the 'big three' of Roger Federer, Rafael Nadal and Novak Djokovic. However, outsiders are capable of causing surprises, as Gustavo Kuerten (2000) and David Nalbandian (2005) have both demonstrated.

ATP Winners

The winners list is as distinguished as they come, with the likes of Jimmy Connors, John McEnroe, Bjorn Borg, Andre Agassi and Pete Sampras all having won the tournament in years gone by. Top of the tree overall are Federer, Sampras and Ivan Lendl with 5 victories each - so Federer could become the outright leader of the ATP World Tour Finals winners list this year.
