Roger Federer pleased with form and fitness

Roger Federer is happy with his form and fitness during the ongoing Australian Open.

The former world number one was speaking following the conclusion of his quarter-final victory over Juan Martin Del Potro earlier today.

"I'm moving well, I'm serving well, I'm hitting the ball clean," Federer told reporters. "Today I thought on a very hot day with fast conditions, I was able to control the ball.

"I didn't really struggle too much on his serve today for some reason. I was able to return great, and I think that was a big key.

"Then I think I was serving the right way, even though I didn't have the highest first serve percentage."

Today's match was Federer's 31st consecutive Grand Slam quarter-final.
