 Roger Federer is confident his Wimbledon experience and supremacy on grass will enable him to hold off the growing challenge of Rafael Nadal in today's final. The Swiss ace is favourite to lift a fourth successive title but the 20-year-old Spaniard goes into the match with the upper hand, having beaten the world No 1 in four finals already this year, most recently at the French Open a month ago when he thwarted Federer's bid to hold all four Grand Slam titles. However, their last three meetings have all been on Nadal's favourite clay surface and Federer, who has won his last 47 matches on grass going back to the first round of Wimbledon in 2002, believes the young Spaniard is still getting to grips with the faster game. "It's obviously different going into a match like this when it's on Centre Court in Wimbledon," he said. "It's different than going into the French Open final, because there it's on clay, which is his favourite surface. This is my favourite surface and that obviously changes a little bit. "He's never been in the Wimbledon final and I don't know how much it really means to him. "But I've been in this position and maybe I can draw some experience out of it." Nadal, who had never been past the third round before this year, has surprised himself with his run to the final and is happy to accept the role of underdog. "He is the best on this surface, for sure," said Nadal, who is the first Spaniard to reach the Wimbledon final in the Open era. "He is the favourite by far. But I'm going to try my best, as always. I need to play the best match of my life for the victory." The two men have experienced contrasting runs to the final, with Nadal having spent six hours longer on court, and Federer admits he is full of confidence. "I have never reached the final of any Grand Slam as easily as this Wimbledon, so I hope I can finish it off in style," he said. Federer is the fourth man to reach the Wimbledon final in the Open era without dropping a set and is aiming to emulate Bjorn Borg in winning the title with an unblemished record. The three-time Wimbledon champion is in his fifth consecutive Grand Slam final, having won at the US Open last year and the Australian Open in January, and is out to win his eighth Grand Slam title. Win or lose, the pair have confirmed the world rankings and Federer believes today's final will be only the latest of a series of head-to-head clashes on the big stage. "It's great we play back-to-back Grand Slam finals," he said. "I think it's very exciting for the sport." |
