Rafa Nadal said he does not expect to be in good enough shape to mount a serious challenge at the season-ending ATP Finals after being beaten by Tommy Paul at the Paris Masters on Wednesday.
Nadal was up a set and a break against the American but was unable to seal the win, eventually losing 3-6 7-6(4) 6-1.
The 22-time Grand Slam champion's defeat in Paris came in his first singles match since the US Open fourth round in September, after which he took time off for the birth of his first child.
He has never won the ATP Tour's finale, which runs from Nov. 13-20 in Turin this year, though he has reached the final twice.
"I'm excited about playing, even if it hasn't been a perfect couple of months for me," Nadal said.
"It's true that for the last five months I didn't spend enough days on the Tour. I don't even say competing on a tennis court. I say on the Tour. Practicing with the guys. That's what I need ...
"For me (it's) difficult to imagine now arriving in the World Tour Finals in enough good shape to win a tournament that I didn't win during all my tennis career."
