Nadal is showing every bit of his 38 years out there.

Head bowed as he sits in his chair at the changeover, sweat drips down his nose. He exhales heavily.

The Spaniard is gassed.

Father Time is knocking on the door and Djokovic seems intent on sending Nadal into retirement.

In other news, Billie Jean King found a seat. Next to Snoop Dogg. A collab we’d all love to see and never thought we would.

I’m starting to think I’m a bad omen.

I was covering the cycling time trial when Josh Tarling got a puncture.

And then that happens to Tom Pidcock…

The stream on BBC iPlayer and red button is now switching to the individual eventing finals, after GB won the team competition earlier today.

There are three GB riders involved, with the top 25 from the team competition qualifying. Both Laura Collett and Tom McEwen qualified in the top four so there are more medal hopes there.

No doubt about it… Novak Djokovic has come to play.

It feels like Clubber Lang giving a hiding to Apollo Creed.

Djokovic is no young buck, of course.

But, unlike Nadal, he is still at the pinnacle of the sport and his blows are too big for the Spaniard to take.

When Djokovic thumps a forehand winner down the line for a 2-0 lead, Nadal can only clap his strings in admiration at the quality his opponent is showing.

Nadal isn’t helping himself, though. A double fault sets up a break point which he saves but a wild forehand wide allows Djokovic to move a double break ahead moments later.

Victor Koretzky of France is the leader by 10 seconds from South Africa's Alan Hatherly as they begin their fifth lap.

GB's Charlie Aldridge is fifth, 20 seconds off the lead, with Tom Pidcock battling his way up to sixth.

It is still all to play (or race) for.

Team GB's cyclists aren't having much luck with their tyres.

Josh Tarling missed out on a medal in the time trial earlier this week because of the same issue.

It's pretty hard to ride the tough sections when you've got a front puncture. I think it's so difficult because Tom will be feeling frustrated, but when you are frustrated, you don't race well. You have to be calm and not race angry.

The conversation about GB coming into this game was the context of their qualification position, if they do proceed, which indeed they should.

It’s about trying to avoid Australia and New Zealand, and at the moment it is a crash course heading their way.

It is better news for Pidcock's GB team-mate Charlie Aldridge, who is up to fourth.

The drama.

Tom Pidcock was looking so good when I saw him a few moments ago.

But NO! A puncture? How much is that going to cost him? He’s now 36 seconds behind. But we’ve seen him do some special stuff before…

Remotes at the ready!

If you want to continue watching the mountain biking it is switching back to BBC One.

Tom Pidcock switches on the afterburners out in front, with a three-second gap to Mathias Flueckiger and Victor Koretzky.

Koretzky then cuts that down to just a second as they cross the line for the fourth lap.

The gauntlet has been thrown down.

Just as it was yesterday, the atmosphere at the mountain biking is insane.

Fans legging it left, right, up, down just to get as many glimpses of their favourites as they can.

Pidcock’s in an excellent position at two laps down with Charlie Aldridge not far behind. Six to go!

The lead has been changing a little bit.

The riders are trying to squeeze through and manoeuvre themselves around.

It's nerve-wracking to watch. These guys are going so quickly through the obstacles. They want to go down in the quickest time with the shortest route they can take.

They must know when their opportunities will come to overtake when there is enough width on certain sections on the course.

Mathias Flueckiger of Switzerland is the leader at the end of the second lap with a time of 21.40, but Tom Pidcock is right on his heels.

This is bubbling up nicely.

Djokovic is just about doing enough out there. No more, no less and everything going along in Mission Olympic Gold Medal.

It's taken very little out of him.

Nadal avoids the bagel (a 6-0 set) to the delight of the Roland Garros crowd.

The biggest roar of the afternoon comes as he cranks his side of the scoreboard into life.

Nadal is adored here and that would have been hard for his fans to stomach.

Djokovic misses out on a career first there - taking a set 6-0 off his long-time rival.

While he’d have loved to have done that, Djokovic is more than content with the 39-minute breadstick.

A heads up that our additional channel on red button and iPlayer is switching from the tennis to Great Britain v South Africa in the women's rugby sevens.

The men's mountain bike cross country is on BBC Two, but will be switching to BBC One after the news.

Mark: A bit of a mismatch, so far, on the Philippe Chatrier court Rafael Nadal just isn't on the same level as Novak Djokovic at the moment

Jonathan Jurejko
BBC Sport at Roland Garros

This is getting out of control for Rafael Nadal.

The Spaniard has barely played over the past couple of years and is carrying a thigh injury at the moment.

He’s nowhere near the level of Djokovic, who has dominated in every area.

The 24-time Grand Slam champ from Serbia is showing no mercy and breaks again for 5-0.

Not the contest which a packed Court Philippe Chatrier was hoping for.
