Novak Djokovic proved what a worthy champion he is when he came back from the dead to defeat Italian teenager Lorenzo Musetti in there last round … but does he have enough gas in the tank to go another long match with Matteo Berrettini?

The 34-year-old Serb was down two sets, albeit in tiebreakers before unleashed that inner strength to take then next two sets, losing just one game.

But locking horns with another Italian, Berrettini, that could be a very different challenge.

The Italian has a powerful game with big serves and even bigger forehands. If he can find the right mix against Djokovic then he has a chance.

Then there’s the question over Djokovic having g to push himself through five sets to get here against Berrettini, who advanced to the quarterfinal via walkover the Roger Federer withdrew.

It will be a gruelling clash and one that could go either way. Djokovic has yet to hit top form but Berrettini has there arsenal to really hurt the Serb if he underperforms.
