Federer's bid to complete the full set of Grand Slam titles was scuppered by arch rival Rafael Nadal in the French Open final, but he arrives here as a red-hot favourite to win a fourth straight title in SW19. Fatigue looks the only thing likely to stop the 'Fed Express' who after two weeks' hard slog in Paris then went to Halle (and won) to equal Bjorn Borg's record winning streak fo 41 matches on grass. It was 2002 when Federer last lost on this surface and few would bet on that run being halted here.
