LONDON - Rafael Nadal says he is happy with his form this year, despite suffering a shock early exit at Wimbledon to an "inspired” Lukas Rosol.The 11-time Grand Slam winner lost 6-7 (9-11) 6-4 6-4 2-6 6-4 in the second round to world number 100 Rosol.Nadal, 26, had gone into the tournament on the back of winning a seventh French Open title, and he said: "You win, you lose. The last four months were probably the best of my career."I just played an inspired opponent.”After Rosol had moved into a 2-1 lead, Nadal appeared to have regained control of the match when he won the fourth set to take the contest to a decider.But a delay while the centre court roof was closed appeared to disrupt his momentum, and in the end the Spaniard succumbed to Rosol’s sustained big hitting."For sure [the decision to close the roof] wasn’t the best one for me but that’s what it was and I accept it,” added Nadal.Nadal’s exit was his earliest at a major since he was ousted at the same stage of Wimbledon in 2005 by Luxembourg’s Gilles Muller.Next month he will return to Wimbledon to bid for a gold medal at London 2012, and he plans to take a bit of a break from tennis before then in order to rest and recuperate.
