Former star sees more slams for federer

Don't count Roger Federer out yet. That's what Pete Sampras says, anyway, and he would know.

Although the Swiss ace - who surpassed Sampras' former record of 14 major titles on the way to 16 of his own - seems to have lost his Grand Slam form, Sampras said "it's still possible" Federer could win more.

"I feel like Roger can still win majors," Sampras said. "He's got some troubles now. But he's got a tough number (of Grand Slam titles for others) to catch up to. Nadal certainly has a chance, but physically it's not easy for him to do it."
