World number one Rafael Nadal insists he isn't playing well enough to win a sixth French Open title as a Wednesday quarter-final looms with Roland Garros bogeyman Robin Soderling.
The 24-year-old Spaniard, who has cut a world-weary figure both on and off the court, complaining he sometimes feels as if he's been on tour for "100 years", is a champion under pressure.
World no.2 Novak Djokovic, on a staggering 43-match unbeaten run, is tipped to take the Spaniard's Paris title, as well as the number one ranking, after picking up the Australian Open and six other titles this year.
"I am not playing enough well to win this tournament. That's the truth," said Nadal, who needs one more French Open to equal Bjorn Borg's record of six.
"You have to be realistic. But I have won here five times already. I don't have an obligation to win six."
Nadal's mood would not have been improved by seeing Djokovic's scheduled quarter-final opponent, Italy's unseeded Fabio Fognini, pull out with a torn left thigh muscle.
While the Serb rests until Friday's semi-finals, Nadal returns to court on Wednesday to tackle Swedish fifth seed Soderling for the third year in succession in Paris.
