Last year, Federer was arguably the best player on tour with Djokovic and perhaps Murray just below. He regained the World number 1 spot from Novak, an incredible feat, won a seventh Wimbledon title and won more tournaments than any other player. His win percentage, at 88.1% was the best on tour and he defied so many critics by beating Djokovic comfortably at the All England Club and then crushing home favourite Murray in the final. He also reached at least the quarter final in every grand slam, coming incredibly close to the final at both Flushing Meadows and Roland Garros. If anyone ever needed proof that Fed isnt going away any time soon, just look at last year.
