Arsenal manager Mikel Arteta admits that he hopes Bukayo Saka will be fine after sustaining another knock.
The winger, who scored in a 2-0 win over Sevilla, went down awkwardly after challenging for a header.
However, his manager alleviated concerns about the English attacker, stating that it may be a minor problem.
Speaking in his post-match press conference, Arteta stated: "It was just a kick and I was told by the physios on the radio he wasn't happy to continue.
"So he will have some discomfort but hopefully I am going to assume he will be OK."
Arsenal next take on Burnley in the Premier League at home on Saturday.
