LONDON - British tennis star Andy Murray says he has Roger Federer running scared ahead of this year’s Wimbledon championship.

Murray reckons Federer has become a sore loser after failing to beat him in their last four meetings.

The British No 1, who won his first grass court title at Queen’s on Sunday, is now breathing down Federer’s neck in the world rankings.

And the five-time Wimbledon champion is clearly starting to feel the heat, having consistently criticized Murray’s style of play.

Federer has accused Britain’s brightest hope of negative tactics and failing to develop his game.

“A lot of the times I’ve beaten him, he has said negative things about me. His comments, though, don’t make me feel I need to change my game. I’ve won my last four matches against Roger and feel that will have a bearing if we meet again at Wimbledon this year. I will take a lot of confidence from those results,” The Sun quoted Murray, as saying.

“Much of the time, I think he has been very frustrated against me. That shows the style and tactics I play against him are working. He’s not used to losing very often and, when you’re upset, you sometimes say things you don’t mean,” he added.

Murray has faced Federer eight times during his career, winning six of those meetings.

Murray insists he is not feeling any pressure in the build-up to Wimbledon fortnight and has even invited comparisons to the late Fred Perry by unveiling a special retro-look kit.

This year marks the 100th anniversary of Perry’s birth and 73 years since he became the last British man to win the men’s singles tournament. (ANI)
