Murray blows the top

The British number one criticised Wimbledon officials for not giving him enough notice that he would be playing his match against Switzerland's Stanislas Wawrinka under the new Centre Court structure.

When Murray took to the court with Wawrinka the weather was dry and Murray said: "It's tough when you're warming up, getting ready for the match outside and it's dry and then get told you're playing under the roof."

The roof had been put to its first competitive use mid-afternoon when showers halted the previous match between Dinara Safin and Amelie Mauresmo.

He continued: "The decision should be made before that match (Safina's) is finished so they can let the players know in a decent amount of time what conditions they are going to be playing under.".

And he also moaned about the humidity levels inside Centre Court which he claimed affected his serve during his 2-6 6-3 6-3 5-7 6-3 fourth round victory which saw the match end at 10.38pm with the Wimbledon hill still packed but in total darkness.

He said: "We were sweating so much. Both of us were trying to get white towels because your hands were drenched. When I finished it was like I had been in a bath. It slowed things down a lot and I struggled to serve because it wasn't coming off the strings that quickly.

Murray, however, who now plays Juan Carlos Ferrero in the quarter final opn Wednesday, admitted the experience could now be an2 advantage if he plays under the roof again.

He said: "I know now I have to change my game if I play under the roof and I know the way the court plays."

"I believe I can win Wimbledon. That's not changed since the first match. But I'm going to have to play great tennis to do it."
