Four Things We Learned From Arsenal's Comfortable Europa League Win Over FK Ostersunds

Nacho Monreal and Mesut Ozil both got on the scoresheet as Arsenal cruised to a 3-0 win away at Swedish side FK Ostersunds in the first leg of their Europa League Round of 32 tie on Thursday night.

Despite the routine nature of the victory, there were still a number of things to take away from the match. Here's what we learned.

1. Arsene Wenger Important of the Europa League to Arsenal

Alexandre Lacazette may have been injured and Pierre-Emerick Aubameyang cup tied, but that didn't stop Arsene Wenger from naming a strong side for the fixture.

Henrikh Mkhitaryan and Ozil both featured, marking the German's first Europa League game of the season.

With the Gunners eight points adrift of the Champions League places, Wenger is clearly aware that winning the Europa League is Arsenal's best hope of a return to Europe's premier competition, and was taking no chances here. 

Expect plenty more strong lineups in the Europa League this season, although perhaps not in the return leg, which falls just three days before Arsenal's Carabao Cup final clash with Manchester City.

2. Mesut Ozil & Henrikh Mkhitaryan Already Have a Connection

When Arsenal completed the signings of Mkhitaryan and Aubameyang in January, many were excited to see the former Borussia Dortmund teammates link up again.

In the absence of Aubameyang on Thursday night, it was one of Mkhitaryan's new teammates that the Armenian demonstrated his connection with in Sweden.

Both Mkhitaryan and Ozil caused problems for the FK Ostersunds defence all evening, with Mkhitaryan adding two more assists to his already impressive tally since joining the Gunners. 

The latter in Sweden, a pinpoint one-two with Ozil to set up the German for Arsenal's third was proof of just how clinical, and vital, these two will be to Arsenal between now and the end of the season. 

3. Danny Welbeck Must Do More to Regain His Starting Place

The absence of Lacazette and Aubameyang offered Arsenal's forgotten man, Danny Welbeck, the chance to prove his worth to the Gunners once more.

Instead, the Englishman flattered to deceive. The striker struggled to make an impact on the game, something which in fairness was probably not helped by the cruise control nature with which Arsenal managed the game.

When they did get forward however, Welbeck struggled to get involved. The striker was often found drifting out wide, and put two good opportunities wide. It may be an ominous sign for Welbeck that with seven minutes to go he was taken by Wenger to be replaced by 18-year-old Eddie Nketiah.

4. This Tie Was a Reminder of the Opportunities for Englishman Abroad

Few will have expected FK Ostersunds to get much out of this tie, the fact they have simply got here is an achievement in itself, given that when their manager, Englishman Graham Potter, arrived six years ago, the club were in the fourth tier of Swedish football.

Since then they have enjoyed three promotions and a victorious Swedish Cup campaign, before progressing from a Europa League group that included Athletic Bilbao and Hertha Berlin to earn a shot at one of Europe's better known sides.

Much has been made of the appointment of tried and tested ageing managers in the Premier League rather than given new managers a chance this season, and the deserved attention Potter's success is now getting is proof that sometimes a move abroad will bring more success than waiting for a chance at home.
