Tim Henman is raving about Djokovic’s ability to shift direction in the rally.

That backhand winner zips past the Russian, who can barely turn back to look at what he’s contending with here.

It’s a break back after the break back. 4-2.

Medvedev still dancing around his backhand to launch an impressive forehand to Djokovic’s backhand side.

Djokovic then unable to loop a forehand back inside the line. 15-30.

And suddenly, another double fault! Remarkable timing, a sniff at a break back for Medvedev, 15-40.

Silence! Nobody can quite believe it, a gift from Djokovic and Medvedev is back in this set, and perhaps the match.

Medvedev now looks tired and perhaps a little sorry for himself, he’s break point down.

Djokovic jumps on the second serve and then dictates the rally from that moment onwards.

Medvedev going long and that is surely that?

That was machine-like from Djokovic, no let-up, he moves one clear and it gets just that little bit harder for Medvedev.

As we approach the three-hour mark, both men look noticeably fatigued.

But Medvedev will have to dig that little bit deeper to salvage this match.

A lovely moment at the start of the third game. Medvedev slips, grazing his left elbow.

Djokovic hurdles the net and offers him an arm up, though he declines. 15-15.

Djokovic is the all-time leader in grand slam history for reaching the final.

He’s played in 72 grand slams and is in his 36th grand slam final. Remarkable.

Medvedev is alive! Sprinting to the net and planting a whipped forehand crosscourt to move to 40-0 and that’s a game to love.

Both men clearly taking a breather after that gruelling second set.

Djokovic injury update: It looks like general fatigue, as the Serbian is stretching both legs and doing a series of lunges before serving.

A bit more zip on those serves, it’s straightforward enough. You would hope that isn’t a trend or maybe the game will be over rather quickly.

Medvedev is getting some serious massage therapy on that left shoulder. He looks in some pain, real anguish across his face.

But the fresh t-shirt is on, a new wristband, can he rally in the third?

The backhand is relentless, crosscourt, just peppering Medvedev, who would not break for so long.

The Russian was begging him to go down the line, but he wouldn’t and it paid off. 5-5.

And suddenly Djokovic has set point out of nowhere, in a tiebreak where he’s barely held on.

SET! He’s done it, remarkable resilience from the Serbian, and Medvedev looks crushed. 2-0 and now within one set of that magical 24th slam title.

Djokovic, with 23 written on his trainers, steps into the backhand cross-court, but that nets. The 18th unforced error of the set, Medvedev only has 15.

2-0 to the Russian. The mini-break is there. It’s 3-1 to Medvedev and he smashes into the net, could that be costly? He still leads 3-2, now for Djokovic to serve.

And a booming first serve just when he needs it, Djokovic pulls level, 3-3. Both men take a drink.

Another exhibition in the extraordinary, Djokovic unable to return the drop shot with another, as the ball spins wide. 5-4 to Medvedev.
