PARIS: A fired-up Novak Djokovic repelled a stirring fightback by Italian Matteo Berrettini to claim a 6-3 6-2 6-7(5) 7-5 victory on Wednesday to set up a mouth-watering semi-final showdown with defending champion Rafa Nadal. The 34-year-old bellowed a series of frightening roars after completing a victory that at one stage looked like a formality but became increasingly fraught as Berrettini threw the kitchen sink at the Serb who becomes only the second man to reach 40 Grand Slam semi-finals after Roger Federer.
