Djokovic values rivalry with Nadal

Novak Djokovic believes his rivalry with Rafael Nadal that is currently dominating tennis can only be good for the game.

The pair met in a fourth successive grand slam final at the French Open at the weekend, the first time two men have ever played each other in every final in the space of a year.

Nadal, the victor in a rain-delayed final to earn a record seventh Roland Garros title, has now reached the final at the last five grand slams while Djokovic has been in six out of seven finals.
