Ivanisevic has fired down 150 aces in his five matches to date and as Bailey explains, the biggest task Henman faces is simply returning the ball.

"You have to accept that as far as his serve is concerned, there will be games when you will not even touch the ball.

"Tim has to go out with the mentality that he will get one or two opportunities and it's a matter of taking them when they come.

"It may be in the first game of the match or he may have to wait until the tie-break.

"But whenever it is, he has to be alert enough and mentally strong enough to take his opportunities."

In 1993, Bailey began to get a feel for where Ivanisevic's serve was going as the match wore on, but evidence from this year suggests that Henman may not be so lucky.

"I was told that he liked to serve down the middle and cross-court, which he did, and that helped me, but this year he's mixing up his serve more than in the past."

Ivanisevic likes to keep rallies short and as a result his return is equally strong.

But there are aspects of the Croat's groundstrokes that Bailey worked on, as it is key to "make sure that you hold all the time".

"I went wide on the deuce side and mixed it up on the advantage side," recalls Bailey.

When people think of Ivanisevic two things spring to mind - his serving and his volatile demeanour.

But Bailey believes that at the same time as rejuvenating the former, Ivanisevic has cut out the latter.

"He's enjoying himself so much more, he is more under control and he doesn't put so much pressure on himself," Bailey explains.

"Goran's been told he needs shoulder surgery and he has come into Wimbledon with the feeling that it may be his last and he's just seeing how far he can go.

"He's playing loose, serving well, returning well and the odd unpredictable shot shows that he's really enjoying himself."

Ivanisevic has always been one of Wimbledon's crowd-pleasers and if anything his new found "freedom" has only increased his popularity with the crowds in 2001.

But against Henman the Croat will not be the Centre Court favourite and Bailey regards the battle for the crowd as a key contest.

"The crowd will be a big part of the match and Tim is finally starting to use them like he should.
