If there is a player who has impressed me during the first week of Wimbledon, it has to be Venus Williams. She usually starts tournaments quite slowly, but she has been totally concentrated and focused on her game.

Crucially, she has committed the least amount of errors of all the top players, and that is not something you often say about Venus. Her sister Serena, on the other hand, has been struggling against players she would normally beat quite easily. And Jennifer Capriati's serve is still a concern for me, to the extent that it could affect her title chances.

In the men's tournament, I thought Greg Rusedski looked great against Andy Roddick and played one of the best matches I have seen him play. Tim Henman is not playing nearly as well as he did last year but he has not been tested yet. Lleyton Hewitt has been very impressive. He reminds me of Jimmy Connors - he grinds the ball, he's got a great return of serve and he's got great groundies on the grass. Like everyone else, I've been surprised by the amount of upsets in the men's draw but it just shows you the power of a good serve. But I think it could be good for the game: you have seen pretty much the same players winning titles over the last few years, so now maybe it's time for a new era. Jeff Morrison is now the only American left, and he has a tough match against Sjeng Schalken in the third round, but I am not too worried about that.

Americans are brought up on hard courts, in the same way the British players are brought up on the grass. Pete Sampras and Andre Agassi are in the twilight on their careers and they are going to find it tougher and tougher to win majors. Andy Roddick, who has a great future, is not quite ready to win on grass: he was simply outclassed by Rusedski who is totally comfortable on the surface. Roddick is only 19 and is going to need time to gain confidence on grass.
