Kieran Tierney will miss Arsenal's visit to Leicester City tonight due to a groin strain.

The former Celtic defender had to pull out of Mikel Arteta’s squad ahead of their Premier League victory over West Ham at the weekend and it is understood that he will not be fit for tonight's Carabao Cup clash.

Speaking after Arsenal's win over the Hammers, Gunners boss Arteta said: "Kieran is fine. He had a little muscular discomfort in the last few days.

"He tried today and worked in the warm-up but he wasn’t feeling comfortable today.

"We could not control it. We believed that he was going to be fit but during the warm-up, in the last 10 minutes, he said he wasn’t feeling OK.

"We had to make a decision. We were prepared just in case and Kola [Sead Kolasinac] came on and had a good game."

Tierney's groin injury is not thought to be serious and Emirates medical staff are hopeful that he will return to full training later this week.
