Rafael Nadal says his belief that too many tournaments are played on hard courts hasn’t changed with his success on the surface this year - he’s simply given up trying to change the system.

The Spaniard, who reclaimed the No 1 ranking from Novak Djokovic this week, has a 27-1 record on hard courts this year, including his second US Open crown and three Masters titles.

He said on Tuesday at the Shanghai Masters tournament that he still believes too many tournaments are played on hard courts, but he’s finished trying to influence ATP policymakers.
