Bravo DT!

The Austrian yorks one into the feet of Nadal.

40-30.

It's been sapping stuff from the pair so far.

Thiem then pulls it back to deuce after Nadal fails to pick up a half-volley near the net.

Some absorbing rallies, some thrilling exchanges and we're only in the third game.

Wayne Ellis: Thiem has caused Rafa more problems on clay than probably anyone else, but this is RG. Think it’ll be closer than last year, but Nadal to win in 4.

Estaban: 6:4 6:2 6:3 Nadal.

Jules Mason: Hard not to see today's @rolandgarros, external final as a 3 set win for @RafaelNadal, external

You've got to hand it to Thiem - he is making Nadal work in these rallies.

But who do you think will be first to blink?

30-0.

40-0 as Thiem finds the net.

This has a different feel to last year's final. Thiem isn't overawed. He's not like a deer in headlights as he was last year in his first major final.

Thiem holds after Nadal twice finds the net.

Nadal is bubbling though.

Any idea who Jorge Prados and Luiz Ruiz - who have travelled over from Madrid - are supporting?

It's the same man who they met near the Eiffel Tower last night...

"We met him on the street," says Jorge. "Although we were expecting him to appear because we knew where he was staying!

"First the security person stopped us but we said 'we've come from Spain to see Rafa'.

"And Rafa told the guys to let us close and take a photo.

"We were nervous, said to him we didn't want to annoy him. Then we wished him luck!"

Thiem makes a double but follows it up with two super shots which send Nadal out wide.

The 'Thiem drop' which confused and upset Djokovic is read by Nadal who responds with his own.

Too good Rafa. Too good.

30-30.

I have to disagree Greg - I think it'll be a three-setter. We shall see.

What do you guys think?

If this first game is anything to go by. This is going to be physical, it's going to be a classic and it's going to be long.

30s each.

Thiem does remarkably well to keep pace with Nadal's groundstrokes in a brilliant rally.

Alas, he comes unstuck before returning long.

Game Spain.

One unruly baby has decided to start wailing, putting Nadal off his stride.

Laughter greets the noise at first.

Then Rafa shakes his head when the kid stretches its lungs again.

Nadal looks at the umpire to ask him to do something. Think it’s the parents who need to take action and head off court...

The Chatrier announcer almost runs out of breath as runs through Rafael Nadal's ELEVEN victories on this very court.

Each year is greeted with an increasing level of applause.

Nadal is very close to the 25-second serve limit already. Last year he got a warning. This year we have the clock.

Is this an indication of who this fan wants to win?

Only two names left on the men's side of the draw board at Roland Garros...

The reigning champion wins the first point of the final with a typical forehand decorated with more whip than ice cream from a van in Brighton.

Play stops due to screaming baby.

Nobody in the history of our sport has won 12 majors at the same tournament.

My heart says Thiem but my mind says Nadal in four.

Zach Kingsbury: Let's go Thiem!!!

Nadal elects to serve.

Here's what "adrenaline-fuelled" Thiem said after Saturday's victory over Novak Djokovic.

"To play Rafa here on this court is always the ultimate challenge, one of the toughest challenges in sports.

"It's an unbelievable opportunity. I said last year that I hope to get another chance in a Grand Slam final and do better then, so tomorrow there is the chance. I think it's really important that I go into the match with the belief to win. That's the most important thing.

"I’m still feeling fine, I’m still full of adrenaline. I’m not going to be tired, I’m ready to leave everything I have out on the court tomorrow."
