Rafael Nadal has said that he is confident ahead of the French Open final against Novak Djokovic.

The Spaniard remains on course for his seventh victory at Roland Garros after his three-set demolition of compatriot David Ferrer.

Nadal said that he is enjoying an "almost perfect" clay court season but admitted that he faces a tough proposition in the form of world number one Djokovic.

"I've been playing well since the beginning of the season," said Nadal. "I am having an almost perfect clay-court season, and we'll see what will happen in the final. It's going to be a very tough match."

Nadal is yet to lose a set in Paris this year.
