Arsenal have lost Kieran Tierney for a month after the Scottish left-back picked up a knee injury against Liverpool last weekend.
The Scottish defender limped off during the game, where Liverpool won 3-0 at the Emirates comfortably.
Arsenal fears that six weeks could be the maximum amount of time out, but the good news is surgery isn’t needed after a further assessment.
Mikel Arteta has refused to comment whether Tierney will play for Arsenal again this season.
“We have to make sure first that he doesn’t need any surgery, which it doesn’t look like,” he said.
The timeframe will be that. It could have been worse because the action looks quite scary, but he seems a bit better, and the damage was not that bad, so at the end of the day, it is not the bad news we could have been waiting for.
“We are going to have to go day by day and see how Kieran is feeling, then when he gets close to playing time and how he is feeling we will make that decision.”
"He hasn't recovered well, he wasn't comfortable and we can't take the risk"

Tierney’s injury is the only out-and-out left-back in the Gunners’ squad and will miss the Europa’s critical games against Slavia Prague and vital Premier league games.
Arsenal will, however, welcome back Granit Xhaka, Saka, and Emile Smith Rowe for the first leg.
