Mark Philippoussis has insisted he has nothing to fear from Tim Henman when they clash on centre court in the fourth round today.

Philippoussis, the 10th seed, came through the longest one-day match in Wimbledon's history on Saturday, defeating Holland's Sjeng Schalken 20-18 in the fifth set after five hours.

In contrast eighth seed Henman brushed aside Morocco's Hicham Arazi in three sets.

The British number one will also have the vast majority of a packed centre court crowd to cheer him on as he tries to become the first home winner since 1936.

But Philippoussis, nicknamed 'Scud' because of his huge serves, is not worried about anything Henman can throw at him.

The 23-year-old Australian said: ''It's not that he's unbeatable. Obviously he loves it here, he's going to get a lot of support, but I love it here too. It's not like I'm intimidated or anything, I'm feeling good.

''I think it's good to get through a match like that, a tough one, because if it gets tight I know I've been there before and I'm going to feel good. I'm looking forward to it.

''I'm expecting to go out there and win, I'm not going to go out there and think anything else. I know what I'm capable of doing and I've come here to win this.''

Philippoussis also has no doubts that he can recover sufficiently from his five-hour marathon thanks to a new fitness regime getting him away from the playboy lifestyle he had been associated with.

''I've wanted to try to set myself in the right direction and if it's not going to happen here, it's going to happen, I know, down the track. With the amount of training I've been doing, its putting me in the right direction," he said.

''I've got a day off and I've worked hard, this is what working hard is for. I'm going to be fine and ready to go.''

Henman and Philippoussis are the third match on centre court, with defending champion Pete Sampras against Sweden's Jonas Bjorkman first up at 1pm.

Sampras, seeking a record seventh Wimbledon title and 13th grand slam crown, came through the first test on his injured shin on Saturday, coming back from losing the first set to beat compatriot Justin Gimelstob in four sets.

Second seed Andre Agassi, a possible semi-final opponent for Henman, takes on Germany's David Prinosil on court one while Australian Pat Rafter faces Sweden's Thomas Johansson.

The other fourth-round ties see South African Wayne Ferreira play Vladimir Voltchkov of Belarus, ninth seed Thomas Enqvist against Jan-Michael Gambill and Marc Rosset against Germany's Alexander Popp.
