Safin leaves China with swipes at Berdych and Roddick

On Monday, Roddick called on the ATP to reduce the length of the men's season or risk shortening the careers of top players such as Roger Federer and Andy Murray.

"In 2004 we had this discussion in Olympic Games with Roddick about it and they were blaming me that I'm playing too much," said former world number one Safin.

"And I was saying that the season is too long. We should make it shorter. And the guys, they jumped on me, like I was the one who was wrong.

"So look at all of them -- everybody is falling apart. Everybody is getting injured left and right, and everybody is complaining the season is long. It takes six years to realise that something is wrong?

"They just have to deal with that, not when they are 21 and ambitious and want to make money. They have to think a little bit with their brains and to make the career a little bit longer."
