Good afternoon and welcome to Eurosport's LIVE coverage of the French Open men's singles semi final between Novak Djokovic and Stefanos Tsitsipas. We'll bring you all the action as it happens at Roland Garros.

The world number one is through to a fifth Roland Garros final where he will face Nadal for the French Open title! But Djokovic had to work for this! Tsitsipas showed incredible fight and resolve to come back from two sets down and force a decider. In the end, the Serbian's quality and muscle memory of how to win these matches shone through.

The world number one is now a game away from his fifth Roland Garros final. What does Tsitsipas have left in the tank? His leg seems to have become a bit of an issue in this deciding set. He's wincing in between points.

Tsitsipas looks a beaten man now as Djokovic takes a firm grip of this deciding set with a double break. The world number one has upped the speed of his groundstrokes, while Tsitsipas is struggling to keep up at the baseline. Is there one last twist in the tail here?

Three games in a row for Djokovic after he breaks down Tsitsipas with his forehand. All of a sudden, the Greek looks weary. Djokovic also looks tired, but he seems to be dealing with it a bit better. He has been in this situation many times before, of course.

A drop shot winner and Djokovic has the break in this deciding set! Tsitsipas was just too far behind the baseline after a backhand-to-backhand exchange and the world number one spotted it. Is that the moment that sends Djokovic towards the finish line?

A love hold from Djokovic and that should steady the world number one. Just a quick note - Djokovic has never lost a Grand Slam match having had match point. Will this be the first time that has happened to him? Tsitsipas looks the better player at the moment.

Another huge hold from Tsitsipas! Djokovic had a break point against the Greek's serve, but Tsitsipas has found consistency with his groundstrokes and this sort of hitting is just too big even for the world number one and all his defensive capability.

We are going the distance! An ill-judged and mistimed drop shot from Djokovic lands in the net on set point and Tsitsipas takes the fourth set to send this to five! Wow. This has been an incredible comeback. Djokovic had match point against the Greek in the third set!

This is lights out tennis from Tsitsipas at the moment. It feels like he is playing on the edge, but it's working for him as he saves three break points to move within one game of taking this the distance. How will Djokovic respond?

A comfortable service hold for Djokovic. What a crucial point in this match. A break here for either player and it will either be game, set and match or a fifth set. Tsitsipas isn't showing any signs of backing off. He has been so aggresive since midway through the third set.

What resistance from Tsitsipas. Djokovic had two break points on the Greek's serve, but couldn't take either of them. A break here for Tsitsipas and he would be serving to take this match to a fifth set.

The world number one steadies himself and holds serve relatively comfortable. Tsitsipas came through a five-setter in the first round. Does he have enough in the tank to get through another one? Both players look rather fresh at this stage, but something to keep an eye on.

What a massive hold from Tsitsipas. Djokovic had a break point against the Greek's serve and has cranked up the dial on his returning, but Tsitsipas nudges the scoreboard againt to edge ahead in this fourth set. He's not going away any time soon!

That was Djokovic's best service game for some time as he levels things up again in this fourth set. No sign of a sore arm from the Serbian. Of course, that has been an issue for him recently. The problem has been his focus and the improving level of his opponent.

And now Djokovic breaks back to love! Is that the swing in momentum the world number one needed to accelerate towards the finish line in this fourth set? He had lost his focus (and his forehand) in recent games, but Tsitsipas' run of games ends at five.

This feels like a completely different match now! Djokovic is broken to love and Tsitsipas has this match by the scruff of the neck! The world number one has lost his focus, but the Greek has also raised his level substantially!

It's now four games in a row for Tsitsipas and he has the momentum behind him now. That was a mini battle at the start of this fourth set and it's the Greek who comes through. If he can keep his first serve percentage high, he has a real chance here.

Amazing! Tsitsipas has snatched the third set and we're going to a fourth! Djokovic had a match point on his serve just three games ago, but he was broken twice in a row and the Greek is well and truly in this! A stunning forehand winner from Tsitsipas up the line saw him take the break point!
