But what about this guy?

ROCK.

There were some good performances from Arsenal in the first half. Mesut Ozil and Pierre-Emerick Aubameyang looked sharp going forward.

Matteo Guendouzi was impressive in midfield again.

But what about Alex Iwobi? Unai Emery is expecting him to sign a new deal before the window closes but he's not quite got going today.

Thoughts on the first half?

And that was the last action of the half.

Mesut Ozil's free-kick is lofted in towards Shkodran Mustafi. The centre-back gets decent contact on the ball with his head but it bounces inches wide of the far post.

One minute to go until half-time.

Henrikh Mkhitaryan should make it 2-0. His first touch is excellent as he brings a high ball down in the box but his shot is straight at Gianluigi Buffon.

It's a fairly comfortable save for the keeper and Mkhitaryan will need to do better than that to beat Buffon.

Christopher Nkunku almost lights up the stage. He twists and turns, escaping tackles from Hector Bellerin and Mohamed Elneny in the process, before curling it goalwards.

It's heading towards the top-right corner but just skims over the crossbar.

Christopher Nkunku tries to slip it into Timothy Weah down the left but the pass is too heavily weighted and Shkodran Mustafi watches it out for a goal-kick.

The PSG forward shrugs his shoulders in frustration and trudges back.

Fred Honsa: Didn't Unai say he wanted five captains? Well he's got them now or maybe about to.

Alec Georgen's cross somehow makes its way through to Timothy Weah in the box. The PSG forward gets in front of a flat-footed Sokratis Papastathopoulos but can't direct it on target.

That was too easy.

And Arsenal do get a chance.

Adrien Rabiot gives the ball away in the area but Mesut Ozil is in an offside position just as he is about to pull the trigger.

Arsenal have taken the intensity down slightly. They seem content to pass the ball around, going through the motions and waiting for an opportunity to arise.

Bernd Leno is called into action. Mesut Ozil carelessly gives the ball away on the edge of the box and Timothy Weah has a pop.

It's hit fiercely but straight at the keeper so it's a comfortable save for Leno.

Things are looking comfortable for Arsenal now. Matteo Guendouzi is spraying the ball into deep positions, looking for the runs of Henrikh Mkhitaryan and Pierre-Emerick Aubameyang.

One goes too long but the youngster is applauded by his team-mates.

It was Matteo Guendouzi who played Pierre-Emerick Aubameyang in with a lovely lofted ball over the top.

Gianluigi Buffon to the rescue! The veteran pulls off a terrific stop to deny Pierre-Emerick Aubameyang from close range.

The Arsenal forward was one-on-one in the box and he twisted the defender inside out to create space to shoot on his left.

Sead Kolasinac played the full 90 minutes against Atletico Madrid and perhaps he's feeling it. His crossing hasn't been up to it so far but he's getting in all the right positions.

Moments after one of his crosses goes wayward, PSG look to counter through Timothy Weah but he's clattered into by Shkodran Mustafi after attempting a flashy flick.

Since scoring, Arsenal have started to run riot. Thomas Tuchel may need to change things up here.

Azzeddine Toufiqui is short of options and tries to curl it in from distance - his second attempt from a similar position - but it doesn't test Bernd Leno.

Pierre-Emerick Aubameyang thought he'd scored Arsenal's second. Mesut Ozil plays in Henrikh Mkhitaryan but he's offside when he slips it into the middle for Aubameyang to slot it home.
