Roger Federer has claimed that the extra week off has helped him prepare for Wimbledon better than ever before.

The seven-time champion, who is seeking to become the most successful man to have ever played at the tournament, has not won a Grand Slam for three years, but he is confident he can mount a serious challenge.

He told The Guardian: "It's probably been the best preparation I've ever had for Wimbledon, because we have a week more on the grass. I'm sure I'm not the only one saying that.

"It's changed everything. The body might feel it after Wimbledon but the good thing is you can heal problems you might have carried over from the French rather than taking them right away on to the grass.

"I've been playing well for a year now, and it's been a good last week. Winning Halle has given me the extra confidence it's going to take me to win this title."

Federer will meet Bosnia's Damir Dzumhur in the first round.
