Mallorca (Spain): Fourteen-time Grand Slam winner Rafael Nadal said he is not sure if he will win a major tournament anytime soon and add to his tally.

Nadal struggled to rediscover his best form lately and his dominant reign at the French Open came to an end during a barren year without a major triumph. He has won two Wimbledon, nine French Open, two US Open and one Australian Open titles to cement his place among the greats of the game.
