Success all in the head for Nadal

RAFAEL NADAL believes tonight’s US Open final against Novak Djokovic will be a match played principally in the mind.

The pair have been the standout players of 2011 and the meeting at Arthur Ashe Stadium at 9pm will be their sixth of the season, all of them in finals.

So far Djokovic has won the lot, including a momentous victory in the Wimbledon showpiece in July, after which Nadal admitted his legendary mental powers had failed him when he most needed them.
