Matteo Arnaldi starts with a couple of double faults and an unforced error - perhaps an early sign of nerves as he starts his first Grand Slam quarter-final?

Two break points for Matteo Berrettini, who puts away an overhead smash to make the perfect start.

This is the first time that Matteo Berrettini and Matteo Arnaldi have played each other at tour level, and it's in a French Open quarter-final.

Berrettini is in a sky blue polo shirt and black shorts, Arnaldi is also in sky blue - but a vest rather than a shirt - with white shorts.

Matteo Arnaldi is into his first ever Grand Slam quarter-final - and he's done it the hard way.

The 25-year-old has spent 17 hours and 42 minutes on court, breaking the record for longest time en route to a major quarter-final since the ATP Tour began recording match times in 1991.

His past two matches, against Frances Tiafoe and Raphael Collignon, have gone to five sets.

Matteo Berrettini is no stranger to the latter stages of a Grand Slam - he got to the Wimbledon final in 2021, losing to Novak Djokovic, and this is the seventh time that he's got to at least the last eight of a major.

Many expected that Wimbledon final appearance to be a platform for sustained success for the big-serving Italian, but his career has been hampered by numerous injury problems since then.

It's the world number 105 against the world number 104 tonight and it's the first time two men ranked outside the top 100 have met in a Grand Slam quarter-final since 1991.

And it's only the second time that two Italian men have met in a major quarter-final. The first was at last year's US Open, when Jannik Sinner defeated Lorenzo Musetti.

The depth in Italian men's tennis is pretty strong right now.

Wednesday's night session will be getting under way shortly as the last of the four men's quarter-finals is played under the lights on Court Philippe Chatrier.

I'm going to make a bold prediction: an Italian named Matteo will win.

We're going to hit pause on this live page for a little while.

But don't worry, we'll be back at around 19:15 BST for the last quarter-final of the day as Matteo Berrettini and Matteo Arnaldi go head to head in an all-Italian match-up.

See you very soon!

Finally from Flavio Cobolli, speaking on Court Philippe-Chatrier after his quarter-final victory about his semi-final preparations: "I do my same routine as I do every day. I go to dinner with my friends and I go back and I sleep."

On the all-Italian semi-final between Matteo Berrettini and Matteo Arnaldi: "Two good friends on the tour, so I wish them good luck and I hope they enjoy the match."

"Best week of my life. Now I miss something, so I have to fight again."

Flavio Cobolli, speaking on Court Philippe-Chatrier after his quarter-final victory: "I think we played two different matches today. The first set was incredibly windy. It was really tough to play. I went to the toilet to think a bit and to change something.

"This is the best court I have ever played in my life. I experienced my best tennis and I said to myself 'to fight' because I felt like this is the chance of my life. I have to give everything in my matches, and today I did it, so I am really happy."

On the wind: "Tennis is like this every day it changes. This week it changed a lot. We have to accept everything. I think I did that today and that's why maybe I won this match."

"The best week of my life," says Flavio Cobolli in his post-match interview.

He will make his top 10 debut next week unless he loses in the semi-finals and Jakub Mensik beats Alexander Zverev in the other last-four tie.

Flavio Cobolli's win means two Italians will meet in the semi-final of a Grand Slam for the first time in the Open era.

We will find out this evening if it's Matteo Berrettini or Matteo Arnaldi who join him in the last four.

A double fault on the first match point...

Flavio Cobolli isn't going to let this opportunity pass him by. The Italian races to a 40-0 lead and he's got himself three match points.

Over to Flavio Cobolli. Can he serve out the win and reach his first-ever Grand Slam semi-final?

What sort of pressure must Felix Auger-Aliassime be feeling now?

He's got to hold serve to stay in the match.

No problem, says the Canadian. A timely love hold keeps him alive.

Flavio Cobolli whips a cross-court winner out of Felix Auger-Aliassime's reach for a 40-0 lead.

The fourth seed claws his way back to 40-30, but Cobolli shuts up shop after getting lucky with another net cord to slam an angled forehand past the Canadian.

He's one game away from a maiden Grand Slam semi-final.

Felix Auger-Aliassime can only smile. He left that Flavio Cobolli forehand, thinking it was going wide, but it landed well within the court.

But he regains his composure and grabs control of the game to hold to 15 and stay within one game of the 10th seed.

Winner after winner from Flavio Cobolli, who is letting rip with his forehand. An easy hold to love.

The Italian is on a roll.

He gets it! Is that the decisive moment?

Flavio Cobolli shakes his fist in celebration after watching Felix Auger-Aliassime's forehand go long. The fourth seed heads back to his chair with his head down, looking rather dejected.
