"The problem with British tennis is that there's always so much negativity," Murray told the Sun.
 

"There's always someone complaining, whether it's a coach moaning about the players or players criticising coaches.

"The attitude of some of the players is terrible. Why can't everyone just get on with things?"

With Murray absent because of an injured wrist this year's Wimbledon has been Britain's worst for 17 years, with no home player making it into the third round of either the men's or women's championships.

Murray's criticism echoes that of Boris Becker, Tim Henman and British tennis chief Roger Draper over the past few days.

Murray praised fellow Scot Jamie Baker's attitude, saying: "Players with his type of discipline and work ethic should get the funding, not the ones who try to blame something else and say, 'it's this guy's fault or that guy's fault'.

"Just get on with it. Tennis is an individual sport. The funding you get is a bonus. We are very lucky.

"The people who are allocating it say a lot of the players are spoilt but surely these players have been made spoilt.

"We have to stop making excuses. It's not just about numbers. It's about finding the kids who want it."
