LONDON (AFP) - Andy Murray admits his attempt to win Wimbledon for the first time will be fuelled by his vision of what it would be like to serve for the title.

Murray, the world number three, is expected to mount a serious challenge for the mens singles title at the All-England Club when the tournament gets under way on Monday.

The Scot won his first grass-court title at Queen's last week and he can't stop thinking about what it would be like to reach match point in the Wimbledon final.

"I've thought about serving for the title - but the closer you get to a grand slam the less you think about it," he told BBC Radio Five Live.

"In the gym is the time I think about those things - to find a reason for putting in the hard work - and when you're going through it on the running track.

"Sometimes you feel sorry for yourself, you are finding reasons for doing the training. When I get tired and out of breath I think, 'I'm doing this so I can last long enough in the fifth set of a grand slam' - focusing on the last point and hoping your opponent misses."

Murray, seeded third behind Rafael Nadal and Roger Federer, reached the quarter-finals at Wimbledon last year before being thrashed by eventual winner Nadal.

Bolstered by many hours of physical training in the searing heat of Miami after that defeat, Murray is now a far more dominant player. He has already beaten Nadal and Federer this season and admits his confidence is sky-high.

"It is good for confidence any time you win tournaments," he said. "To win your first event on grass is nice - I had never made a final on grass.

"At Queen's I felt more comfortable on grass than I have in the past. I played well there and I feel good.

"It is a tough thing to do because you are only playing one or two tournaments on grass a year and all of the best players normally play."

Most players have to survive at least one gruelling five-set match en route to a Grand Slam success and Murray, who reached the US Open final last year, believes he can last the pace as well as anyone.

"I needed to get even stronger to be able to play back-to-back five-set matches over the whole tournament," he said.

"After Wimbledon last year, I went to train in Miami for three or four weeks and that is pretty tough weather to train in around this time of year.

"That made a difference going into the hard court stretch and I made my first slam final. I have that belief that I can play the whole of the slams now.

"I would love to win Wimbledon one day, there is no question about that, but I try not to think about it too much."

If Murray could do with a little luck in the draw to aid his bid to become the first Britsh man to win Wimbledon since Fred Perry in 1936, but the Scot isn't worried about who he faces when the draw is made on Friday.

"You cannot worry too much about that because if you want to win the event, then you are going to need to beat the best players anyway," Murray said.

"You would always rather avoid dangerous floaters, guys like Ivo Karlovic, because they can beat anyone on any given day, but you try to not worry about it and prepare as best as you can."

Murray is likely to play most of his matches on Centre Court, raising the prospect of getting used to indoor action if bad weather forces Wimbledon officials to use their new roof, but he won't lose sleep about the change in conditions.

"Any time I have played indoors, it does change things. There is no wind, I am sure it will get quite warm in there," he said.

"I watched a bit when they did the roof-opening event and it felt quite muggy.

"But because there will be less wind, no atmosphere to worry about, no sun or anything to deal with, it kind of makes it a little easier to play. I kind of grew up playing indoors, so hopefully I will like it."
