PARIS – Rafael Nadal remains top of the ATP tennis world rankings with the 32-year-old 17-time Grand Slam winner enjoying a comfortable margin over his eternal rival the Swiss Roger Federer.

Serb Novak Djokovic is in 10th position, after turning round from a long slump as a swathe of American tournaments swing into view ahead of the US Open starting late August.

South Africa’s Kevin Anderson, runner-up at Wimbledon, comes in at number five, a more forty-five points ahead of sixth placed Grigor Dimitrov of Bulgaria.
