Djokovic holds after a great backhand down the line. Cecchinato, the world number 72, had a break point which if he had taken it would have seen him serving for the French Open semi-finals.

It vanished, as does that game. Tie-break or Djokovic taking us into the fifth set? Let's find out.

The pair trade on the baseline, right up to the point where Cecchinato dumps his backhand halfway up the net. A chance wasted.

If he had won that point he would have been serving for a place in the French Open semi-finals. The sort of moment that can change a match and leave a player with a restless night's sleep.

Break point for Cecchinato.

30-30 on the Djokovic serve after a backhand return creeps long. A half-chance for Cecchinato. One you get the feeling he has to take.

And there it is. Cecchinato wins his third game in a row and we are back to 5-5. Is the shock back on? Now are the doubts and the pain in the body largely with Djokovic and not his opponent?

Remember, not too long ago Djokovic had chances to take a 5-1 lead in this set. Cecchinato is now a point away from making it 5-5. 40-30

Nine unforced errors in this set from Djokovic, eight from Cecchinato. Tired minds, tired bodies, thrilling match.

A couple of unforced errors from Djokovic, a sweeping forehand winner from Cecchinato and that is the break he needed, and one that just did not look on the cards very recently.

This set looked finished, it isn't, but Cecchinato still needs to hold his serve next time out.

Break point for Cecchinato. Vital, very vital.

Djokovic two points from this being two sets all. The rain threatened us, but has not stopped us.

A hold for Marco Cecchinato but now comes the hard part, trying to break the Djokovic serve. He has to or this fourth set is done and dusted.

Nick's gone for the conspiracy theory route..

Nick ÜTA: Hmm, Djokovic suffering from a terrible injury, then suddenly shaking it off when he starts to perform... Has that ever happened before? #disappearinginjury, external

The returns are lacking a bit of pace compared to earlier, the shoulders are down, the energy levels are diminishing. That is another game gone for Marco Cecchinato.

The way this is going you would expect Djokovic to see out the deciding set unless there is a dramatic change of fortunes.

The Italian's next job though is to see if he can extend this fourth set a bit longer. Him to serve, 2-5 down, but 2-1 up in sets.

Novak Djokovic belts down an ace, only his fifth of the match, for 30-0.

That looked like being the fourth set being practically over. Novak Djokovic had chances, let them all slip through his fingers and Cecchinato holds his serve eventually.

Djokovic still holds a break though in this fourth set and is ready to go in game seven.

The drop shot, so many times a delightfully disguised drop shot, has often come to Cecchinato's recovery, but not this time. The ball nestles in the net and Djokovic moves to break point. However, he then goes long. As we were.

A sweeping forehand into a vacant area of the court after a wide serve to Djokovic's backhand saves that break point. Back to deuce.

Djokovic break point.

Marco Cecchinato won't have played too many five-set matches in his career. He may have to here. But will it be tonight or will they have to come back tomorrow?

We are at deuce in the sixth game of the fourth set after a delightful Djokovic lob over a tired-looking Italian.

The rain is here, but it is not too heavy so we continue, much to Novak Djokovic's delight.
