Federer back in top form

The Swiss, who has never dropped a set against the claycourt specialist in their six encounters, won 6-4 6-0 and will meet either France's Richard Gasquet or 2003 French Open champion Juan Carlos Ferrero of Spain for a place in Sunday's final.

Following two exchanges of breaks, Federer stepped up a gear and broke decisively in the ninth game when Ferrer sent a forehand wide.

The second set was a mere formality for the Swiss, who wrapped up the win in 58 minutes.

"I'm really happy to have won my 500th game here in Monte Carlo," Federer said in a courtside interview.

"David is a very good player. Beating him 6-4 6-0 on clay is very good for me. I like to play against him: he is a good player and I win. It was a good test."
