Tennis icon John McEnroe has hit out at Rafael Nadal for slow play following the Spaniard’s victory over Novak Djokovic in the French Open quarter-finals.

Nadal, 35, beat his arch-rival 6-2 4-6 6-2 7-6 in a thrilling late-night match on Court Philippe-Chatrier which did not finish until 1:15am local time on Wednesday.

‘No other player has had to deal with more adversity,’ said the American.

‘It is unfair, I’ve got to say that. This guy has turned lemons into lemonade more often than any player in the history of tennis, and if you don’t think it bothers him, you’re nuts.
