The French Open is the only Grand Slam title to have eluded Novak Djokovic and the steely-eyed Serb has adopted a philosophy of reverse psychology in a bid to claim the coveted crown in Paris.

World No 1 Djokovic has lost twice in the final at Roland Garros and believes he can end his barren run on the clay surface by reining back any hint of self-imposed pressure or specific goal-setting.

"The difference in my approach to my goals and priorities between now and a couple of years ago is that I don't put too much pressure on myself," Djokovic said on Thursday at Indian Wells, where he is seeking a fourth BNP Paribas Open title.
