Rafael Nadal believes his quarter-final demolition of Andy Murray was his best performance at Wimbledon.
The 22-year-old Spaniard brutally took apart Murray 6-3 6-2 6-4 to set up a last-four showdown with either Rainer Schuettler or Arnaud Clement.
Murray could not deal with Nadal's serve - he failed to force a single break point - or his powerful forehand.
And the Spaniard believes that there is now little he needs to work on if he is to finally win the Wimbledon title.
"If I play like I did against Andy, especially the second set, there are not a lot of things," he said.
"With the second half of the first set and especially the second set, this was probably my best match here.
"I think I'm doing a lot of things better than last year. The slice is better. My position on court is better. I'm playing more aggressive with the forehand all the time, and the backhand is feeling good."
Nadal has reached the Wimbledon final in 2006 and 2007, only to lose out on both occasions to world No.1 Roger Federer.
However in last year's five-set epic, Nadal came agonising close to ending the domination of the Swiss ace at SW19.
"Last year was close," said Nadal. "Only one more point and probably I would have the trophy in my home. It was disappointing to have another plate.
"I'll have to play very well if I want to win this tournament. I am playing well, but I don't know if it is enough."
