• Rafael Nadal has no doubt Federer will be better next year than he was this year.
"I don't have any doubt that he will be playing better than what he did this year," the Spaniard told a news conference at the Paris Masters, where the two could clash in the final.
"No doubt about that. His talent allows him to keep being one of the favorites, to keep winning the best tournaments of the year.
"So talking about if he's able to be back or try to be back in the No. 1 (spot), I think it's not his goal, because at the end he already has been there. He has been in the top positions of the ranking for a long time."
