JUDY Murray has revealed she is not finding it any easier watching her son Andy at Wimbledon despite his success last year.

She roared him on to victory as he made it to the quarter-finals on Monday but his matches are still painful viewing for his mother.

When asked if sitting in the players' box was less stressful than last year, she said: "No! I think there is a huge expectation level out there from everybody, obviously because he's won Wimbledon and he's won the US Open and the Olympics.

"I think everybody is expecting him to do well."

Mrs Murray, who was speaking at the launch of the Miss Hits programme which encourages young girls to play tennis, added that her son has the experience to win the event again.

"It's a very, tough sport. The strength in depth in the men's game is enormous," she said.

"But he's been playing at Wimbledon since 2005, he knows what to expect. He's always handled it really well and he's 27 now, he's older, more mature. He'll be out there trying to do it all again.

Murray is gearing up to take on Bulgarian Grigor Dimitrov, whose girlfriend is Maria Sharapova.

The Scot is heavily favoured with odds of 2/7 to win.

A spokesman for bookmaker Paddy Power said: "Whilst we'reall for a bit of cupid love out on the courts, we're hoping that Murray rains on the Dimitrov and Sharapova parade and drenches their hopes of Wimbledon success."
