Rafael Nadal said he body is still adapting to the indoor hardcourt conditions after he booked a semi-final spot at the Paris Masters.
Nadal overcame compatriot Pablo Carreno Busta 4-6, 7-5, 6-1 to keep his hopes of a maiden title in the event alive, although he knows he is also still some way short of his best.
That, though, is just down to the changing conditions from outdoor clay to indoor hard, and he believes he just needs a little more time on court.
"Now is a moment to be happy because semi-finals are a positive result for me after a long time without playing on indoor hard," Nadal told the press.
"The body needs to adapt to the hard surfaces and the stress of the high-level competition
"I think matches like today, like the first day, like yesterday's second set helps.
"So he was winning his serves very comfortably, so when that happens you are able to play more aggressively with less stress on the return, so I think that was the main problem.
"I think later I started to return a little bit better in the second half of the second set.
"I had a couple of chances and then I finally had the break, won the second set, and after that I was returning better, I was not hitting the ball bad, so it was the moment to push and I was able to make that break.
"It's true that in the break he made a couple of mistakes but I saved some very difficult balls I think and then I was serving well during the whole match."
