Novak Djokovic hailed Rafael Nadal as a “great champion” after losing an epic late-night French Open quarter-final, but added he was “not surprised” by his rival’s recovery from a debilitating injury. 

Nadal, the 13-time champion at Roland Garros, clinched a memorable 6-2, 4-6, 6-2, 7-6 (7/4) victory to reach his 15th semi-final at the tournament.
