Roger Federer has shrugged off the impending danger posed by Rafael Nadal's seemingly unstoppable march towards his world number one spot.
"I feel good, I'm focussed," said the Swiss, who has been number one since February 2004 and who defends his Cincinnati Masters title this week.
"I'm not focussed on Rafa, he's on the other side of the draw. Of course he's been playing great and is on an unbelievable winning streak."
Nadal claimed a seventh title this season on Sunday as he defeated Nicolas Kiefer in straight sets for the Toronto Masters trophy.
"We're back on hardcourt again and it's hard to keep winning. But what he's doing is terrific," said Federer.
The world number one said that fighting off Nadal cannot produce any more stress than a Wimbledon final, where he won five titles in succession before falling to his Spanish rival in an epic five-set final earlier this month.
"There's always pressure, but I expect to win my matches and tournaments. I've had that four or five years. It's nothing new.
