You'd be mistaken for thinking Arsenal had already reached the Europa League quarter-finals after their impressive 2-0 win at AC Milan.That was, of course, never exactly the case and the return leg always prompted a difficult psychological situation for the Gunners and one Arsene Wenger was more than aware of before kick-off on Thursday night. The Frenchman mused: “Europe gives you a psychological problem. When you have won away from home, you have to finish the job at home but it is not easy because it always puts the team who is playing against you in the position of having nothing to lose.”He's not wrong and, as a result, Wenger fielded a strong side for the clash at the Emirates, even if his game-plan was somewhat undermined by Laurent Koscielny's early injury.Andre Silva threatened the Arsenal goal in the opening seconds and while the north London club recovered from the early wobble, nerves in the defence remained.

Arsenal endure a tricky start v AC Milan

AC Milan took advantage of it. The Rossoneri flew into the lead in the 35th minute virtue of Hakan ÇalhanoÄŸlu who beat David Ospina with a dipping long range effort.

Nevertheless, Arsenal levelled things up before half-time with Danny Welbeck winning a penalty under controversial circumstances before tucking it home himself.

It was a relief for the Englishman who has struggled in recent weeks, yet he wasn't the only Arsenal player hoarding the plaudits against AC Milan.

The centre of the praise laid with Henrikh Mkhitaryan who impressed Arsenal fans with not only his typical technical skill, but a remarkable work-rate that even reminded some of Alexis Sanchez.

Fans rave about Mkhitaryan's work-rate - comparisons to Alexis

Take a look at the reaction below:

Since his involvement in the Sanchez swap deal with Manchester United, Mkhitaryan has experienced a steady start to life in north London.

However, his performance against AC Milan seems to be one of his finest under Arsene Wenger and he's endeared himself to Gooners with endless runs on the left wing, right wing and down the centre.

His connection with Welbeck won the home side a penalty and his link-ip player with Mesut Ozil has caused all sorts of problems for the Rosseneri in the final third.

Arsenal have themselves a brilliant playmaker and a certified workhorse.
