66. Well, this is an absolute nonsense.
The referee has been sent to the pitchside monitor to review a potential penalty that nobody - absolutely nobody - had appealed for.
A shot from Achraf Hakimi moments ago was saved by David Raya at his near post.
But replays picked up the slightest graze off the fingers of Myles Lewis-Skelly as the shot went through to the goalkeeper, and now the home side are about to be awarded a spotkick.
63. Donnarumma makes another sensational stop to deny Arsenal!
This time the brilliant Italian keeper flies to his right to tip over a super Saka shot that looked to be curling into the top corner.
It feels like another goal is coming, but will it be through Arsenal's persistence or via Paris Saint-Germain's threat on the counter.
60. Arsenal turn up the set-piece gas.
Within a matter of minutes, Saka and Odegaard have both whipped dead balls underneath Donnarumma's crossbar.
On both occasions, the goalkeeper and his defence manager to deal with the danger, albeit far from convincingly.
57. Some sensational footwork from Vitinho on the byline is surprising for two reasons.
Firstly, the skill. It's as good as anything we've seen tonight and sees him drifts past three Arsenal players.
Secondly, the commentators failed to mention the player's loan spell at Wolves which has now become customary.
56. Myles Lewis-Skelly has had a difficult evening and now he's on a yellow card.
Struggling to keep tabs on Bradley Barcola, the young Gunner bundles his opponent over from behind right under the nose of the referee.
53. For perhaps the first time tonight, Nuno Mendes goes rampaging down the left.
The Portuguese full-back looks up and clips a pass into Desire Doue inside the box; the French teenager takes a lovely first touch to control and then tries to caress it into the far corner but fails to get the right swerve on the ball.
50. Timber prays and looks to the heavens after being penalised for a sliding challenge on Doue.
I'm not sure any divine intervention could have helped him out there though, he was bang to rights.
48. On TNT Sports, Darren Fletcher and Martin Keown are currently roleplaying a phonecall between Neymar and Kylian Mbappe, asking each other why they never tracked back out of possession.
I'll be honest, it's been a long day and it's too late for this kind of nonsense.
46. Arsenal have 45 minutes to keep their Champions League dream alive.
Mikel Arteta has made no changes for the second period, but will know that something has to happen soon if his side are to meet Inter in the final later this month.
PSG are as they were too, and will take some stopping on the road to Munich.
The bad news is Paris Saint-Germain have lost just one of their last 31 Champions League home matches when leading at half-time (W28 D2).
The good news? That defeat did come against English opposition in a semi-final when they lost 2-1 to Manchester City in April 2021.
Arsenal had a mountain to climb before tonight, now it may as well be the French Alps.
The Gunners have performed well this evening, much better than in last Tuesday's first leg, but the lack of a clinical edge in attack again means they are yet to trouble the scorers.
PSG, meanwhile, showed their ruthlessness by netting a scorcher through Fabian Ruiz in one of their rare yet dangerous forays forward.
45. Saka whips in a brilliant cross from the right that is just begging to be put away...
...but there's nobody there to meet it.
It's Arsenal's main problem in a nutshell, and the reason why another otherwise excellent season is going to end without silverware.
43. The game is held up as Myles Lewis-Skelly is winded by a fierce Desire Doue strike.
It won't be much consolation at this moment, but that was brave defending from the young full-back.
41. Another teasing Arsenal cross, this time low from Rice, is almost perfect for Merino sliding into the penalty area.
Minutes before the break, that would have been a great time to halve the deficit.
39. Arsenal have already attempted 16 crosses in this match, which is higher than their average of 15.6 in the Champions League this season.
No prizes for guessing how they are targeting PSG.
37. Rice and Timber both have fierce shots blocked within a matter of seconds.
You couldn't accuse the Arsenal players of giving it their all. It's just that PSG have performed brilliantly at both ends of the pitch.
35. Both Mikel Arteta and Luis Enrique are patrolling their technical areas.
One looks certainly much more animated than the other. I'll leave you to guess which one.
33. These Arsenal players certainly haven't led their heads drop.
Through some hustle and bustle, the visitors manage to make room for stand-in centre-forward Mikel Merino, who steers his shot wide of the post.
30. Arsenal need to keep their heads while PSG adrenalin is pumping.
A Lewis-Skelly mistake looks to have led to a quickfire second, only for a superb last-ditch challenge by Rice on Barcola to save the day.
Don't say I didn't warn you...
27. There is the first goal on the night - and what a stunner it is!
Declan Rice is booked for a foul on Khvicha Kvaratskhelia on the left, and from the free-kick PSG pack the penalty area.
Thomas Partey fails to get distance on a clearing header, but what follows is sublime.
Moving on to the ball, Fabian Ruiz chests down to move away from his marker and then lets fly with a brilliant left-footed strike that whizzes past David Raya and almost bursts the net.
PSG have doubled their aggregate lead, and Arsenal's job just got that much harder.
A pessimistic Arsenal fan may be asking whether Arsenal have already had their "magic moments" in front of goal and blown them. There is still plenty of time, but they need to start taking their chances.
If not, PSG are only going to grow in confidence, and have already had two brilliant chances that could have easily put the tie out of reach for Arsenal.
Mikel Arteta had his hands on his head after Gianluigi Donnarumma brilliantly saved from Martin Odegaard. Is it going to be one of those evenings where Arsenal are brilliant and heroic in defeat?
25. The tempo hasn't dropped since kick-off, but whereas last night you felt the Inter-Barca match could have ended up any score imaginable, you do feel that the first goal this evening will be crucial.
23. Hesitant play from Arsenal at the back gifts possession to the hosts.
It sparks a chance for PSG to counter two-on-one, but after Saliba does well to hold up the attack, Doue shoots tamely at Raya.
It's astonishing that it's still goalless on the night.
