That stunned Anfield in to silence. Smash and grab. A simple ball breaks through the Liverpool back four and Iraola turns back to his bench. It's good build up from Atletico Madrid, back to front very quickly.

Marcos Llorente now has five goals in three games at Anfield.

That is quite something.

Sporting striker Luis Suarez has the ball in the back of the net but it's disallowed for offside.

All Gala so far, with 75% possession and all five shots. Davinson Sanchez had a header saved just before the goal - and since then Leroy Sane shot off target.

That's the first sight of Bradley Barcola as he takes a lofted ball over the top beautifully in his stride but the angle is tight and Jan Oblak makes the save.

Encouraging stuff for Liverpool.

Now Matteo Politano forces a save from David Raya from a shot on the right corner of the box. Good spell from the hosts.

Kevin de Bruyne has been lively for Napoli today. The Manchester City legend slams in a shot from just over 20 yards out which David Raya saves.

Atleti flex their attacking muscles as Julian Alvarez plays it inside but it's left for Alex Baena to strike high into the Kop.

We know he can hit them from there.

That Saka chance happened just after a bit of an Arsenal penalty appeal turned down. Gabriel had a shot blocked and the Gunners suggested a shirt was pulled but not given.

Liverpool take the corner short to Dominik Szoboszlai and he shows great feet to dance his way into the box.

He's crying out for a foul but I think the referee gets it right on second glance.

Now that is a proper save from Dominik Takac.

Dro Fernandez is in acres of space in the box and he picks his spot out but Takac spreads himself really well.

PSG have started this one on the front foot, as you'd expect.

A chance from an Arsenal corner... but for Napoli.

Keeper Alex Meret catches the corner and hurls it forward.

Good run by Napoli midfielder Kevin de Bruyne, who carries the ball for ages before feeding Alisson Santos but he shoots over.

Florian Wirtz threads a ball through the gap for Alexander Isak to race on to. He looks for the square pass into the box but it takes a nick for Jan Oblak to collect.

Few blocked shots in the early stages - with Bukayo Saka and Eberechi Eze seeing their efforts hit a Napoli player.

Mikel Arteta doesn't normally like to rotate his team but he has got real strength in depth and these players need minutes.

We've got our first heated moment and it comes right in front of Diego Simeone.

Pablo Barrios commits the foul on Alexis Mac Allister and there's a bit of a tussle on the floor before Milos Kerkez comes steaming in on Koke.

Liverpool have really started started sharply. One of the traits of an Iraola team is that the first thought is forward.

Alexander Isak looks sharp.

The ball is played through the lines by Alexis Mac Allister and Isak takes it in his stride and knocks it back for Florian Wirtz but the striker had strayed offside.
