Andy Murray maintains his belief that he can win Wimbledon this year after an incredible fightback from two sets down to beat Richard Gasquet on Monday evening.

Gasquet served for the match in the third set but Murray recovered to win 5-7 3-6 7-6 (7-3) 6-2 6-4 and seal a quarter-final against Rafael Nadal on Wednesday.

After a thrilling win in a match that lasted four hours, Murray was asked if he felt he could win the title on Sunday and confirmed: "I've always thought that."

The 21-year-old Scot, who was seeking a first-ever place in a Grand Slam quarter-final, had been in desperate trouble when the eighth-seeded Gasquet took command of the first two sets.

"For pretty much the first three sets he completely outplayed me," said Murray, who had only dropped one set in his three previous matches before Monday's clash.

"He was playing like he had no pressure at all. He was going for his big shots on all the big points, htting the ball so hard and deep that I couldn't really do much.

"And then as soon as the pressure did start to get to him a little bit at the end of the third set, I obviously took advantage of it and came back well.

"The end of the match was absolutely awesome. It was nearly pitch black but one of the best matches ever for sure, for me."

The match moved in Murray's favour when he secured the third set tie-break with an outrageous backhand winner from way outside the tram lines.

"That was obviously huge," he said. "To finish a set like that really got the crowd going and shifted the momentum hugely.

"His head went down a little bit for a few games after that shot."

And Murray admitted he had been lifted by the vociferous support of the 15,000 spectators on Centre Court.

"The crowd were awesome. The whole tie-break and the fourth and fifth sets, once I got ahead they got behind me more than they ever have before.

"He obviously tired at the end of the match and it almost takes your mind off your physical state when you've got so many people behind you.

"I thought they made a big difference in the end, for sure."

Next up for Murray on Wednesday is arguably the toughest challenge in tennis at the moment as he takes on the in-form Nadal, whom he has yet to beat in three meetings.

"I'm going to have to try and recover really well, get enough food in me, enough sleep, and try and prepare the best that I can," said Murray.

"Obviously he's the favourite for the match but I do think that I can win."
