Evening all! They can't can they? Surely they can't! Except this is Arsenal ... of course they can. They can do anything!

Nice from Milan, picking passes to find Kessie 20 yards out. He shoots, but without the power to bother Ospina, and anyway, the ball skids wide.

Meelan set us away again.

That was a really fun half. Milan scored a great goal, but Arsenal, the better team by a fair bit, did really well to up the tempo immediately, even if the penalty award was ridiculous - in that regard, Gennaro Gattuso is currently haranguing the relevant official. The second half should be decent.

Half-time: Arsenal (3)1-1(1) Milan

Monreal fouls someone - Suso I think, but my telly dropped out - and is booked.

Wilshere shoots from 20 yards, and Donnarumma pushes away.

There'll be two added minutes.

Monreal lumps a high cross that Welbeck retrieves, stretching to tap back. Mkhitaryan is there, but forced to generatw all the pace himself, his shot is no bother for Donnarumma.

Great ball in from Suso after moving inside Ozil too easily. But Andre Silva is in an offside position, so when he goes for the ball, the flag goes up - though Ospina still did well to flick away.

Welbeck lanks 30 yards to win the ball off Borini, finds Mkhitaryan who finds Monreal, and Borini pulls him back. He's booked.

There's a bit of noise in the ground now, and Arsenal are playing with more intensity than before they conceded.

Montolivio crosses from the left, the ball bounces up and hits Chambers on the arm, and Milan want a penalty. It isn't, and this time one isn't given; Rpdriguez is booked for opining.

GOAL! Arsenal (3)1-1(1) (Welbeck) Welbeck does Donnarumma with the eyes, looking right, curling left, and Arsenal are back in charge. The more I see the "foul", the less a foul it is, but Arsenal did well to pick it up immediately after conceding.

PENALTY TO ARSENAL! Apparently. Mkhitaryan slides a pass in behind for Welbeck, who runs past Rodriguez, who gets out the road. There's a flailing arm that he does well to remove, so the official behind the goal decides it's a foul. It really was not, which is to say that Welbeck dived and then appealed with righteous indignation.

Wilshere is on the left, he slides a pass back for Ramsey, and he punches a firm shot that's at a nice height for Donnarumma to shove away.

WHAT A GOAL! Arsenal (2)0-1(1) Milan (Calhanoglu) Calhanoglu takes the ball at inside-left and under no pressure from Monreal or Mustafi, edges forwards and from 30 yards, wipes his foot across a belter that catches Ospina by surprise, dipping and hurrying into the far corner! We've got ourselves a ball-game!

The game in Plzen is over, and Sporting have edged Viktoria in extra-time. Meanwhile, Suso takes the ball off Kessie, comes inside and despatches anther cross over everyone and behind.

Suso turns a pass around the corner for Silva, who is terrifyingly slow. He's in a good position here though, at inside-left, only for the flag to go up erroneously.

Mkhitaryan is now on right.
