Two players, Rafael Nadal and Jo-Wilfried Tsonga play in a match to qualify for the semi-final of the 2011 ATP World Tour Finals. One should expect a great match as both know its a now or never moment as the loser packs his bags and leaves. Both Nadal and Tsonga have 1-1 win loss record here with a common thing being that they both have defeated Mardy Fish and lost to Roger Federer.

Rafael Nadal got a thrashing when he lost to Roger Federer in his second match of the round-robin and now needs a win to qualify for the next stage. Nadal, who got the Arthur Ashe Humanitarian Award would be aiming to keep his grinding skills in tact as Tsonga would not be any pushover. Nadal would be counting on Tsonga's errors to prevail in this match. If Nadal wins the ATP World Tour Finals, it will be a first time win at this event for the Spaniard.

Jo-Wilfried Tsonga, holding a 1-1 record would be wanting to continue his dominating form which he displayed with Mardy Fish in his previous match. Tsonga, known for his brutal strength would be happy to display his power and catch the Spaniard off-guard. Tsonga can finish the year at No.6 if he performs well as he is getting tough competition from Czech, Tomas Berdych.

The two compatriots are playing for the ninth time with Spaniard leading 6-2. This year its tied at one a piece with Tsonga beating Nadal at Queen's and Nadal taking revenge during their Davis Cup clash in Spain. The two would be high on confidence as they both know what is at stake. The Bull seeks to subdue the Musketeer, whereas The Musketeer seeks to mitigate the Bull.
