Roger Federer has been drawn in the same round robin group as Rafael Nadal for the ATP World Tour Finals which get underway in London on Sunday.
Federer is seeking to become the first man in history to win six ATP World Tour Finals titles and he's strong favourite after claiming back to back titles in Basel and Paris but the Swiss will face an early clash with old rival Nadal in Group B.
Given the tournament will be held on a fast indoor court, the news will not particularly concern Federer who has had the measure of Nadal at the end of season finale in the past, defeating him in the semi-finals in 2006 and 2007 and 6-3, 3-6, 6-1 in last year's final.
However Nadal has won all three of their matches in 2011, including the French Open final and maintains a dominant 17-8 advantage on head-to-heads.
The group is completed by Paris Masters runner-up Jo-Wilfried Tsonga and Mardy Fish. Tsonga is in superb form at the moment and he could pose some real problems for Nadal when they meet especially as the Spaniard has not competed since the Shanghai Masters at the start of October.
Fish's results on the North American hard courts were outstanding earlier in the year but the American looks like he's run out of gas over the past month and he's also struggling with a few injuries.
