Arsenal manager Arsene Wenger is optimistic Henrikh Mkhitaryan will make a return from his knee injury in two weeks' time.
The Armenian attacking midfielder suffered knee ligament damage in last week's 4-1 Europa League win over CSKA Moscow and there were fears he could miss most of the remainder of the season.
But Wenger struck a more upbeat tone after Arsenal completed a 6-3 aggregate win over the Russian side with a 2-2 draw in Moscow on Thursday night.
He said: 'Yes, [it's a] ligament strain and he should be out for two more weeks.
