Tim Henman has given his cautious backing to plans to build a roof over Wimbledon's Centre Court.

Speculation is rife that the All-England Club are set to finally announce the project at a press conference this week.

Henman admitted that while he had been won over by the benefits a roof would bring, he remained concerned about its impact on the famous grass courts.

The British number one - in Doha where he kicks off his 2004 campaign next week - said: ''If they have got the technology then I wouldn't be against it.

''I used to be against the roof but I've seen it at other tournaments and I think for the spectators and the TV it's important to keep the show rolling.

''The biggest problem has been whether there was the technology to make sure the grass wasn't affected because it would be very humid.

''On a grass court you have got to be very careful because if you damage a court it is not going to repair overnight.''

Henman is relishing the start of the new season after his spectacular end to the last campaign which culminated in a Masters Series win in Paris.

He is looking forward to his new loose coaching arrangement with American Paul Annacone, who will accompany him to a small number of selected tournaments.

Henman added: ''I've spent a lot of time analysing how I felt in Paris and it's something I've learnt a great deal from.

''I've been talking at length with Paul Annacone and I've learnt how relaxed I felt on court.

"At times I think I've been trying too hard and Paris was a good example of how I went out and just let things happen.

''Paul and I see eye to eye and we have a clear idea of how I should be playing. His experience and knowledge of the game can be a big asset for me.''
