Djokovic has not played a match that counted since the semifinal loss to Sinner in the French Open. He showed fight against the world's top-ranked player, but ran out of gas during his fourth-straight loss to the 23-year-old phenom.

Novak Djokovic says he would like to keep playing tennis for several more years. But he also acknowledges it's impossible to know for sure whether he will even be back at Wimbledon again.

After reaching the semifinals at Roland Garros, Novak Djokovic has regained some confidence by proving to himself and the whole world that he can still make a difference in Grand Slam tournaments where he is truly motivated.
