"That game was a little scrappier - there is definitely some tension on the Djokovic side of the court. Murray's movement has been phenomenal. But he will have to deal with a challenge to his concentration because after a tough set there is always a lull. He will really have to focus on holding his serve."

Paul Staveley: I said yesterday that Murray might never beat Djokovic again. I would be SO happy to be made to look stupid this morning!

George Fisher: Male tennis players are simply gladiators! Some of their rallies and length of their matches - just extraordinary.

Mark Page: Weird thought; If Murray wins the French Open he could win the Grand Slam before Novak

Usually Novak Djokovic just mentally shreds lost sets and starts again. But he is having some trouble chasing the gremlins out of his game at the moment.

The Serb wallops away an overhead to beat a stretching Murray for 30-0. But the errors are still pockmarking his game. A forehand into the net and then a double fault help Murray to 40-30. Djokovic's radar is well off kilter. He pumps long again to bring up deuce.

Murray has a chance down the line. Missed. And Djokovic gets through a scrappy game from both players.

Roland Garros:, external Djokovic has a 4-2 record in five-set matches at Roland Garros (23-8 overall). Murray is on a five-match winning streak in five-set matches (5-1 at RG).

"The Parisians rise as one to acclaim that effort from Murray - not even Rafael Nadal managed to raise a sweat on Djokovic and the Scot has got him seriously rattled. The buzz around Chatrier is louder than ever, and those who came for the women's final are getting quite a bonus."

Robert, Invergordon: Well done Andy. Now go for the jugular in the fifth.

Max, Tunbridge Wells: To come out today after the overnight break and play tennis like this is quite simply staggering. Breathtaking hitting.

"Djokovic had his opportunity to put the match away in the third set but Murray hung in. To beat Novak Djokovic from two sets down in the same day would be, I think, beyond Murray. But he has come out fighting today and Novak has made a lot of errors. Murray has won every rally and been running all over the court."

Winning the fourth set any which way was the obvious priority for Andy Murray this morning, but the way he did has been so promising for the decider.

He is pounding Djokovic in the baseline exchanges and has discovered a delicious drop-shot in his armoury.

Joe Dunster: Arghhhh what are you doing to me Murray. Amazing tennis straight off the bat!

Frances Ferguson: All plans may be off for the next hour...

Dean Moffatt: These two are unreal! Best two players in the world right now? Murray would surely have more slams if not for Novak.

And we have a one-set shoot-out!

Novak Djokovic with a laser-guided forehand nicks the first point. Andy Murray misses with his first serve. Creaky. His second lands and Djokovic - coughing up a few errors from the back - goes long.

Murray rushes the net on the next point and Djokovic on the stretch, can only guide his attempted pass wide between the tramlines. 30-15. Two points away.

Make that one. Another unforced error from Djokovic as he strays long off his backhand. 40-15 and two set points.

Djokovic steals the next point. A tentative rally at 40-30, both players tightening up, but it is Djoko who blinks first!

Miles Maclagan
Former coach to Andy Murray and Laura Robson on BBC Radio 5 live

"There is an amazing psychological battle going on. Andy Murray showed his stubborn qualities, telling Novak Djokovic that he is willing to take him all the way. Novak looked to his box as if to say 'what do I need to do to get points off this guy? He's making everything.' We have not seen the drop-shot from Djokovic yet which was so effective yesterday."

This. Just. Got. Interesting.

Andy Murray with the dexterity of a watchmaker as he brings a 32-shot rally to an end with a delicate dropper for 15-15.

The Scot stings an advancing Djokovic on the toes with a superb forehand for 15-30. Is this a chance? It is now!

Djokovic wafts a forehand just wide for 15-40 and two break points. How are those nerves? Djokovic works him over from the back of the court and crashes away an overhead. Back to 30-40.

And Djoko punts long!

Murray is celebrating every point, animating the crowd and trying to turn this into a pep-rally for himself.

He will serve for two sets all next.

Piers Newbery
BBC Sport at Roland Garros

"Murray is seriously pumped up and desperate to get the crowd involved as he had their backing last night, but Djokovic looks as clinical as he did in the first two sets. The stadium is also still filling up, a much more leisurely afternoon feel than the raucous atmosphere last night."

It's the hottest Parisian trend for spring/summer 2015. Andy Murray shows off a fashionable drop-shot and it is oh so chic, dropping perfectly and Novak Djokovic cannot scrape back.

That is 30-0 and Djokovic pumps long for 40-0. Still waiting for our first point against serve. There it is. Djokovic slaps away a drive volley for 40-15. But Murray whips down an ace and clenches his fist up towards his box.

Miles Maclagan
Former coach to Andy Murray and Laura Robson on BBC Radio 5 live

"The quality of this tennis is amazing - just cherish these matches. They keep putting the pressure back on each other. You wondered how Murray would match Djokovic's serve - and he did it. It is important that Murray doesn't let Djokovic take too much control of the rally. We want this match to go on and on."

Leon, Manchester: I'm a massive Murray fan but don't forget Novak's motivation here. He's going for the career slam!! Murray needs to fight fight fight.

Neither player is dominating, but serve certainly is.

Twelve points so far today and all have gone with the man teeing off.

Novak Djokovic racks up another love hold. Andy Murray is backed up to the cliff edge with no margin for error. If he is broken in the next game, then it is curtains.

Let's not think like that though.

Pat Cash
1987 Wimbledon champion on 5 live

"In many ways that hold from Murray was more impressive than Djokovic's. Murray had to beat Djokovic at his own game and is winning the long, long rallies almost exclusively."

Well, a love service game, but that was not nearly as straightforward as Djokovic's one just before.

A mammoth rally in the very first point of Andy Murray's serve. The Scot is stretched thin across the baseline, but gets away with it as he runs down a drop-shot and Djokovic's lob loops long.

Djokovic fires a forehand into the net for 30-0 and then fails to punish a second serve in the next point.

Murray seemed to be getting the upper hand in the rallies on the plus side, but Djokovic was not giving away any free points.

Pat Cash

"Flawless tennis from Djokovic. What a game, to come out in a pressure situation and play like that.
