Novak Djokovic won the Nitto ATP Finals trophy in Torino for the sixth time.
"I don't know what the future holds for me, but I know that in my mind there is still a great desire to win trophies," Djokovic said in the post-match press conference. "Making history in the sport, competing at the highest level around the world, giving emotions to sports and tennis fans. This is what gives me the charge."
