Federer in last four

Roger Federer remained on course for a semifinal clash with Spanish rival Rafael Nadal at the Italian Open after cruising past Tomas Berdych 6-3-, 6-3 in just over an hour on Friday.

Federer has made the final in Rome three times in the past 12 years but has been beaten on every occasion -- twice by Nadal and once by Felix Mantilla, in 2003.

The 33-year-old Swiss could now meet Nadal, the seven-time champion, in the last four if the Spaniard overcomes Swiss Stan Wawrinka in their quarterfinals scheduled for 1900 GMT on Friday.

The old foes have met 15 times on clay with Nadal leading Federer 13-2 on his favoured red surface.

Federer admitted it will be a "huge challenge" to overcome the fancied Spaniard.

"Everyone who has played against Nadal knows he's the best mover on clay, on both sides of the court. He's perfected it," said Federer.

"It's always a huge challenge when you play him on clay."

Although Wawrinka stands between Nadal and a last four meeting with Federer, the Spaniard -- who has appeared in nine of the past Italian Open finals -- is expected to prevail.

Federer admitted his easy win over Berdych had left him feeling comfortable with his progress on the red dirt, less than two weeks before the start of Roland Garros.

"A win like this makes you feel good and confirms I'm on the right track," he added.

"Now, I'm starting to find my feet on this surface, which is usually always the case two to three weeks before Roland Garros when, in principle, I find my best form on clay.”

Earlier, Spain's David Ferrer set up a possible semi-final clash with Novak Djokovic after disposing of Belgian qualifier David Goffin 6-2, 4-6, 6-3 in the quarter-finals on Friday.
