Great Britain's number one Andy Murray has launched a verbal attack on the current tennis schedule.

The 24-year-old said the demands on players are "ridiculous" and that changes are needed immediately.

"I'm being quite open about it, some of the smaller events, because the ATP's messed up the smaller tournaments by giving them 250 points, it doesn't really make much sense to play in, because 250 points isn't going to make hardly any difference," said the Scot.

"But you get good guarantees for going so one or two times a year, it's nice to do that. When we play the Masters Series and the slams, we're playing against the best players in the world every time.

"Sometimes it's nice to go to a tournament when you don't have to kill yourself in every single match. You can gain some confidence from winning matches and maybe winning a tournament. The schedule's messed up and we need to change it."

Murray was speaking after his Davis Cup victory over Gyorgy Balazs yesterday.
