Roger Federer has said he is not that bothered about Serbia's Novak Djokovic closing in on his ranking as world number two.
"I'm going to sleep well for a month. He (Djokovic) is not going to pass me anytime soon," Federer said.
"For me, honestly, ranking two, three, four, five, 25, it doesn't really matter a whole lot, you know. For me it is either number one or being in the main draw," added the Swiss.
Djokovic, who won the Masters Cup in Shanghai on Monday, is just 10 points shy of Federer in the world rankings.
