The world number 1 says he cannot guarantee that he will be fit for the matches. World number one Rafael Nadal said on Friday that he still cannot guarantee he will play in London's ATP Finals starting this weekend. "I'm doing my best," said the Spaniard, twice a runner-up but never champion of the season-ending event. World number two Roger Federer said it would be a blow for Nadal to miss out. He shared jokes with coaches Carlos Moya and Toni Nadal on the court, but appeared frustrated at other moments with an injury that is clearly aggravating him.
