Roger Federer believes that he has finally overcome the mental scars of some damaging losses to end the 2011 season on a high.
Federer beat Jo-Wilfried Tsonga 6-3 6-7 6-3 to win a record sixth ATP World Tour Finals crown, having failed to add to his 15 Grand Slams during the current campaign.
The Swiss, who is 13/8 with bet365 to win one Grand Slam title next year, lost to Tsonga in the quarter-finals at Wimbledon after being two sets up, while he also rued a five-set loss to Novak Djokovic in the semi-finals of the US Open.
Federer said: “Jo played better than me at Wimbledon. Maybe not much, but enough just to come through.
“Same as Rafa at the French Open in the final, Novak in the semis of the US Open. It’s fine to respect that, but I feel when it happens that often, I do have to question myself that maybe I did something wrong.”
