Boxing training would be good for him. The range of exercises would help his fitness but he'd need to sustain it over a long period of time. I think once Andy gets to a high fitness level, he's going to win things. That's the only thing that's missing from his game.

In my view everything comes from the floor, you've got to work on your legs first - if your legs are no good your body is no good. That's why Andy's been cramping up in longer five-set matches. It's like he's going out and fighting a world title every time he plays a Grand Slam.

Sportsman generally have a good idea how to move in the ring. I think I could teach him quite quickly how to handle himself. I think he'd enjoy himself. If he enjoys hard work then he'd like it. That's what boxing is all about.

Andy's got a will to get to the top and a will to win. I've been enthralled by him when I've seen him.
