Relief for Djokovic as he eventually wriggles free to take a 5-4 lead as we reach the business end of a closely fought first set.

The wind is then in Davidovich Fokina's favour as a backhand drops in at the last minute, drawing a grin from Djokovic who, like many inside the stadium, thought that was destined to head wide.

A first serve puts Djokovic in touching distance of another hold, but Davidovich Fokina stays in a rally long enough to watch the Serb send a forehand long. Deuce.

The wind appears to have picked up on Philippe Chatrier. Djokovic waits a moment for a gust to settle down before getting up and running on serve.

Unlucky! Davidovich Fokina lifts a lob over Djokovic, but he is suggesting the wind caught it as it lands just long of the baseline.

Can Davidovich Fokina maintain pressure on Djokovic after such a bright start?

Seemingly unfazed by conceding the break back, the Spaniard returns to his task with a couple of quick points on serve.

Djokovic does get on the board with a clean forehand winner but Davidovich Fokina holds his focus to land a smash which Djokovic is unable to return.

Could Cameron Norrie be coming onto court sooner than we thought?

Elina Svitolina doesn't look so good as she asks to see the doctor.

There are a few concerned looks on faces in Court Simonne Mathieu, particularly that of husband Gael Monfils.

Svitolina is an adopted French player now, having married former world number six Monfils.

The home fans need someone to root for, seeing as all the French players in the singles draws are already out.

Maybe it isn't illness after all, looks like she's after some eye drops.

Novak Djokovic hasn't been allowed to settle yet.

A couple of unforced errors gift Davidovich Fokina 15-30, but the Spaniard pulls a backhand wide at the end of another intense baseline exchange.

Anna Blinkova's serve is definitely packing more of a punch than her Ukrainian opponent's.

The Russian, who has broke Svitolina's serve for a second time, is really stretching the court and is coming out on top of the longer rallies.

Into the net from Davidovich Fokina, and Djokovic's pressure eventually tells.

An immediate response from the 22-time major winner, who brings us level at 3-3 on Court Philippe Chatrier.

Another chance comes around for Djokovic, but that's clever play from Davidovich Fokina.

The Spaniard switches it up, following up a drop shot with a lob which even Djokovic has no chance of getting to.

A solid return from the Serb gives him a third break point, though.

Terrific play from Davidovich Fokina!

He's more than holding his own out there. He handles the pressure Djokovic is putting him under and some clean hitting sets up a final forehand winner. Deuce.

There's that drop shot again!

Alejandro Davidovich Fokina will be wary of how Novak Djokovic tends to respond to any setback.

But here comes Djokovic. Some delicate play at the net from the third seed helps him to 15-30. He's certainly enjoying the drop shots today.

Well then!

Novak Djokovic just can't get rid of Alejandro Davidovich Fokina, who is rewarded for his persistence as he comes out on top in a 20-shot rally, a final forehand winner clinching the second break point.

Long! This time, the Spaniard will have two chances...
