World No 1 Novak Djokovic is looking forward to a new rivalry at the summit of men's tennis after losing a hard-fought French Open final against Spanish clay-court king Rafael Nadal.

The 25-year-old Serb insisted the sport's biggest matchup was still between 30-year-old Roger Federer, holder of a record 16 Grand Slam titles, and Nadal, who at 26, already has 11 majors - topped by a record seven at the French Open. But he clearly singled out Nadal as his main foe.

"We are very young, and we have already played over 30 times against each other, and hopefully we can have many more battles in the next years," Djokovic said.
