Federer: "You lose a set and unconsciously start doing calculations"

Roger Federer was happy at half after his victory at the Masters Cup debut against Jo-Wilfried Tsonga. The Swiss was referring to the loss of a set that can complicate access to the semifinals in the event of three-way tie between players at the end of 'round robin' of the group B. "I had control of the game and suddenly lost my cool. It is difficult to control things when you play against a player who does not rate. Unconsciously I began to make calculations on what to do to stay alive. In any event this is not going on. This is what makes the Masters special, "Federer explained.

Federer, who comes to win in Basel and Bercy, too fast and indoors, says O2 surface is different from previous events contested. "The track, for me, is faster than last year and the ball bounces more." The Swiss choose this year to break the tie with Ivan Lendl and Pete Sampras, only players with him in having five crowns ATP finals.
