Murray injured his wrist in his first match at the Hamburg Masters

There's never a good time for injuries to happen but with two Grand Slams coming up, Andy Murray's been really unlucky.

When you're Andy's age and playing the sort of tennis he's been playing then you're extremely eager to play, especially at Grand Slams.

He's had such a great a start to the year I think he would genuinely fancy his chances of doing well in the French Open.

But you've also got to balance the fact that he's 20, there will be many more Grand Slams and you can't mess around with these sort of injuries.

We need to wait for the full diagnosis but if he didn't make Wimbledon it would be really anti-climactic. I think he could do something really interesting there.

If you take Roger Federer out of the equation Andy's got to be up there with almost anybody else on grass, which I think will eventually be his best surface.

As far as Tim Henman's concerned, the bottom line is he desperately needs some wins.

He's hitting the ball well but he's been a bit unlucky with draws this year and that happens when you're not seeded - you're going to run into some good players.

I thought in the Davis Cup he played very well, looked really sharp. Clay is not his best surface but he did get to the semis only a few years ago.

If Tim could win some matches it would give him great confidence going into the grass-court season John Lloyd

I think that either way Paris is a win-win for him.

Playing the French gets him in great shape for Wimbledon and if he could win some matches it would give him great confidence going into the grass-court season.

If he doesn't, he's played another five-set match, and once he gets on grass it's automatic for him - click, and he's ready to play.

No-one's expecting much from him and that's not a terrible position to be in. He can come in under the radar.

He's in very good shape physically and when you're a pro like Tim and you've been around that long, he knows how to play the damn game.
