Former Top 5 player Mark Philippoussis, who lost to Roger Federer in the Swiss’ maiden Grand Slam title run at Wimbledon ten years ago, says the 32-year-old still has great things left in him.

“There’s no way Roger Federer is finished,” Philippoussis told reporters ahead of the Statoil Masters Tennis, which will be played at the Royal Albert Hall in London. “He’s still a truly great player, perhaps the greatest, and he still moves really well. I think he has one more Slam left in him but it will have to come next year or that will be it. I think Roger can either win in Australia or at Wimbledon next year. The fact that (Andy) Murray’s fitness is a question mark is a factor and that improves Roger’s chances as he lost to him in Australia last year. I’m throwing it out there. It’s a big call but I believe he can do it. Pete Sampras’ last match was to beat Andre Agassi in the U.S. Open final when everyone thought he was finished.”
