There was no surprise when Danny Welbeck was named as the sole striker, as Pierre-Emerick Aubameyang is ineligible. Jack Wilshere was given a spot in the attacking three behind Welbeck, alongside Mesut Ozil and Henrikh Mkhitaryan, and it was the Armenian who surprisingly scored the first goal.

Mkhitaryan cut in and received a ball over the top from Mesut Ozil, and his volley looped off the back of Leonardo Bonucci and past the young but impressive Donnarumma, who had been on a run of clean sheets before this fifteenth minute shock.

This went against the script, with our current form we were supposed to fall away in the face of the terrific stadium, vociferous home support and talented Milan side. We were up for the fight for once though.

Milan nearly made the script come true mere seconds before the goal though. Hakan Calhanoglu was sent clean through as our defence parted like the Red Sea yet again. The Turk only had Ospina to beat, and about twenty yards of turf. Our South American ate up the ground and got rid of the danger, but his exertions left the door open for the AC Milan striker to go to ground. The referee would’ve had a tough decision to make, but luckily, there was no contact and Calhanoglu was honest. Probably to his side’s detriment.

Still, Arsenal were ahead, we should just enjoy the moment. It’s been a real rarity this season. We were also duking it out in midfield, and holding our own. Milan may have been carrying most of the threat, but they were the home side so the onus was on them to win - and to score. It was no surprise that we were doing the majority of the defending.

We were still carrying a threat, and Welbeck was doing his utmost to be a menace, running himself into the ground. Hell, the whole team were putting in the effort we’ve been crying out for over this torturous run of results. Welbeck even came close to getting on the end of some dangerous crosses, especially from a Chambers delivery in the 40th minute.

Two minutes later, Welbeck returned the favour for Chambers, but his lashed effort was saved by Donnarumma. Then, seconds later, Welbeck tested the Italian again, but the goalkeeper was up to the task. Arsenal were finishing the stronger after seeing what Milan could chuck at them, and they would take one big step into the quarter-finals just before half-time.

On 45 minutes, Mkhitaryan rattled the crossbar as our period of dominance continued, Then, a moment of genius from our resident genius Ozil got us a second. His beautiful through ball found the ever-running Ramsey, who finished calmly, seconds before the halftime whistle blew.

The second half began as the first ended, with Arsenal on the attack. This time it wasn’t down to Ozil’s vision, but a mistake by Franck Kessie, who for some reason punted the ball back toward goal and Welbeck used his pace to get there first, only for Donnarumma to save again.

The game entered a scrappy period, with bookings and misplaced passes - exactly what we needed. This wasn’t what Milan wanted, they needed the high tempo but they were being mired by our play in midfield - kudos to Xhaka and Ramsey. Substitutions followed, as both managers sought to adapt to the changing shape of the game, but the match was ticking toward a final resolution, one that we could have scarcely believed before the game kicked off.

Then, Milan had their chance. Bearing in mind this was the 83rd minute and Ospina had made one single stop before this, he again raced out as substitute Nikola Kalinic - former Blackburn Rovers striker Kalinic that is - was clean through. Ospina again made clean contact with the ball and the danger was destroyed. Could this be a clean sheet as well as a win at the San Siro? After the rubbish we’ve witnessed recently?

Yes. We saw out the rest of the game with discipline and rigid defending, so we can do it after all.

We’ve criticised a lot recently, but this was great tactics, great defending and great character. We can question where this has been, but let’s just enjoy the moment. This was not expected, and it means we can dream a little longer about the Europa League.

The job isn’t done. Us being Arsenal and all, it means we always carry the capacity for drama, but for once, we won a first leg of a European tie away from home. We can do this!
