The end of Ostersund's amazing European adventure is bittersweet - a victory against Arsenal at the Emirates, but an exit from the competition.

When Englishman Graham Potter took the helm of the Swedish outfit in the fourth tier of their league in 2010, surely a win against the Gunners in European knock-out competition would have been outside the realm of his wildest imaginations. And after a disappointing first leg defeat for his side, here they were: the full time whistle going and they're 2-1 winner's against Arsene Wenger's side. The 5000 supporters who had made the trip for the game could scarcely believe what was happening, regardless of whether their club progressed or not.

This does not excuse Arsenal, who performed dismally.

A questionable line-out, a lack of urgency and an uninspired display combined to make for a result that would go down in the annals of history as one of the worst ever had it meant Arsenal were knocked out, as was their favourite status in this fixture.

Undeserving or not, however, Arsenal were not knocked out and they will progress to the last 16 of the Europa League, thanks mainly to their performance in the Jamkraft Arena last week, and also to the contributions of Sead Kolasinac, who managed to get what would turn out to be a consolation of sorts on the night.

Before coming to the match itself, it is worth acknowledging the team selection. With the League Cup final against Manchestser City coming up on Sunday, it was presumed by both those who support Arsenal and the wider media world that those expecting to play in that match would be rested for this performance due to the lead gained in the first leg, but it became obvious before kick-off that this was not going to be the case.

Hector Bellerin, Henrik Mkhitaryan, Jack Wilshire and Alex Iwobi all featured from the start, with Granit Xhaka coming on to replace Ainsley Maitland-Niles at the beginning of the second half - all of these players are expected to start against City at the weekend, so the manager has made the decision that they did not require the rest.

Even with the inclusion of several first-team players, it's funny how this game contrasted with the one in Sweden. Arsenal really came out of the traps when playing in Ostersund - the home side were left deflated after just 24 minutes, when they had fallen two goals down. The shoe was very much so on the other foot here, in the exact same situation.

The signs were there from the off. Rob Holding mis-kicked in the first minute, nearly setting up a chance. The Swede's continued to dominate for the opening exchanges, with Calum Chambers particularly assisting this.

The undoubted most notable events of the match happened across a rapid two-minute period where Ostersund managed to find the net not once, but twice to put them 2 goals to the good in the Emirates Stadium.

Midfielders Hosam Aiesh and Ken Sema were the goal scorers, with forward Saman Ghoddos contributing the assists for both. It was a two-minute period that left the home side flustered.

The opening goal stemmed from a Ghoddos ball forward. Holding could not untangle his feet to intercept while Kolasinac was also caught out. Aiesh had the shooting chance and he aimed for the bottom corner, with the aid of a nick off Chambers, he found it.

Ostersund scored again 70 seconds later, after Alex Iwobi had surrendered possession with a heavy touch. The visitors had Sema up against Chambers following Ghoddos’s ball over the top and the danger did not appear pronounced.

Perhaps, that is why Bellerin did not come across to help his team-mate. But when Sema backed into Chambers, worked a little trick and spun away from him, the sirens sounded. The left-sided attacker hammered a low shot into the far corner.

The Gunner's only had one chance in the first half - a Wilshire effort that found its way over the bar. It was a dire half of football that seen the Gunner's go in two goals down at the break.

Roused a little bit for the second half, Kolasinac, reintroduced to the team, thumped home right-footed following an air-kick from Ronald Mukiibi. The defender was one of the stand-out players on the night, and it's good to see him on the scoresheet again. His goal would effectively end the game as a competition, but that's not to take away from Ostersund's display.

One man who was out to impress but sadly didn't was Danny Welbeck, who did not have much impact on the game. The Englishman made mistakes 3 times when in a decent position and won't be remembering the game overly fondly.

Wilshire was substituted after 75 minutes with an eye on the weekend, and Iwobi had to be taken off with what appeared to be cramp in stoppage time, but they had done enough - despite losing the game 2-1, Arsenal are through to the last 16 as 4-2 aggregate winners.

The next thing on Arsenal's radar (and if Thursday's performance was anything to go by, it was on their radar already) is the League Cup final on Sunday. Supporters will be hoping that this was just a blip for Arsenal, and a hugely changed squad is expected, including the reintroduction of Pierre-Emerick Aubameyang up front, who will hopefully cause Pep Guardiola's City some problems.

In terms of this competition, the attention will now turn to Friday’s draw for the last 16 and Arsenal have a good chance of being paired with a decent team from one of Europe’s top five leagues. Lying in wait are Atlético Madrid from Spain; Borussia Dortmund and Red Bull Leipzig from Germany; Marseille and Lyon from France; Lazio and Milan from Italy. Napoli, the Serie A leaders, might be out – beaten by RB Leipzig – but there remains plenty of danger.

One thing is clear. Arsenal will not make it past anyone – let alone fashion a route back into the Champions League by winning the competition – if they play like this.
