World number one Djokovic has beaten Nadal in the last three Grand Slam finals, with his last defeat in a major coming at Roland Garros in 2011 when he fell in the semi-finals to Roger Federer, who went on to lose the final to Nadal.

Since being defeated by Djokovic in the Australian Open final, Nadal has met the Serb twice, winning on the clay courts of Monte Carlo and Rome.

Nadal starts the tournament as clear favourite, he is 6/4 on, but Djokovic isn’t too far behind in the betting, he is priced at 5/2 to win his second slam of the year and his first French title.

Andy Murray will resume his bid for a maiden Grand Slam title when he takes on Tatsuma Ito of Japan in the first round of the French Open.

The Scot faces a tough run to the final at Roland Garros, clay court specialist David Ferrer looms in the quarter finals, before a meeting with the clay phenomenon Rafael Nadal in the semi-finals. His price of 40/1 reflects this tough draw, and the niggling injuries which still threaten to disrupt his game.

Roger Federer at 9/1 looks a smart bet, especially with the money back offer, as he is the only other man to have won the French in the last seven years, such is Nadal’s dominance.
