London: Roger Federer has won one title over the past 14 months, at a low-key tournament this summer. The ATP World Tour Finals in London are his last chance to compensate somewhat for a feeble season.
"I still have another week where I have to give it all. After, it will be long holidays," Federer said after losing to Novak Djokovic 4-6, 6-3, 6-2 in their first meeting this year in the Paris Masters semifinals on Saturday.
The pair was placed in the same group at the season-ending, eight-man finals, which start on Monday.
