Novak Djokovic admits that Andy Murray’s dramatic last-gasp assault on his world number one ranking has rejuvenated a season which was limping into mediocrity for the 12-time major winner. “It makes me want to go on court and fight for every point because there is something to win at the end,” Djokovic said, adding he felt “rejuvenated and regenerated”. If Djokovic reaches next Sunday’s final in Paris he will retain the world number one ranking that he has held for 122 weeks straight, no matter what Murray does in the French capital.
