World number one Roger Federer admitted he was 'exhausted' and badly in need of a break, following his exploits for Switzerland in the Davis Cup.
The 31-year-old helped put his country back in the World Group for 2013 by beating Robin Haase of the Netherlands in straight sets to complete a 3-1 victory for Switzerland.
Last weekend's triumph came at a cost for the Swiss, who conceded he is running on empty. Federer played three times in the tie, winning two singles matches and losing a doubles encounter.
"Absolutely I need a holiday badly. I'm wounded. I'm tired. I'm exhausted, so I need some time off right now and then see where I go from here," said Federer, who is a huge favourite of the sport betting
The 17-time Grand Slam champion has had a busy summer. He reached the French Open semi-finals and the Halle finals, before winning a seventh Wimbledon title.

"Nothing's been decided yet for the rest of the year, even though there's a plan in place. That plan might change," added Federer.
"I just have to now go back to the drawing board and decide what's important, what's most important and what's really important, so we'll see what happens."
