Jet-lag

The one worry for Nadal is the amount of mileage his legs have put in over the past two months, a run that earned him a fourth French Open title, his first Wimbledon title and also the Toronto Masters Series.

“I only got here yesterday and I’m jet-lagged. I’m more tired than normal. Physically I’ve had a lot of matches this summer but in three or four days I will feel different.”

Nadal’s 32-match unbeaten streak came to an end against Novak Djokovic in Cincinnati last week but he can be forgiven one bad day at the office.

Federer’s recent form suggests something more worrying. After his Wimbledon heartache, he then lost in the first round at Toronto and last week in Cincinnati to Croat Ivo Karlovic. He has won only two minor titles all year.
