Arsenal recorded a memorable 4-1 win over CSKA Moscow in their Europa League on Thursday night. The Gunners now hold a comfortable advantage and a chance for easy progress into the Europa League semi-finals.

However, everything did not go well for the north Londoners. Armenian star Henrikh Mkhitaryan was forced out with an injury in the 61st minute against the Russian opponent.

Henrikh Mkhitaryan arrived from Manchester United in January as part of a swap deal with Alexis Sanchez and has done extremely well. He has provided a number of assists in the Premier League and teamed up well along with his former teammate from Borussia Dortmund, Pierre Emerick Aubameyang.

The Armenian and Gabonese have re-established their link-up play in London and have been an exceptional pair together for Wenger’s team.

However, it is now being reported that the former United midfielder has suffered a medial knee ligament injury on Thursday’s outing. The scan is expected to take place this weekend and the result of it will reveal the recovery time depending on the extent and grade of the strain or tear of the ligament.

Arsene Wenger is not positive about the news about the Armenian’s injury and is expected to miss his in-form midfielder until the end of this season.

He has a scan but the medial knee ligament has been touched,

The first impression is not too positive. I fear [it could be several weeks]. I hope I’m wrong.

The Gunners are whey behind in pursuit of the Champions League places but are placed well in the Europa League. A win in that would be enough to take them into Europe’s elite club competition.
