Arsenal fullback Kieran Tierney has admitted frustration with his knee injury suffered last season.

Tierney felt pain in his knee in February but only had a scan on the issue a month or so later, revealing that surgery was needed and his 2021-22 campaign was over.

"I carried on playing for Arsenal, then reported for Scotland duty [in March] and played twice with no problems. I came back completely fine. Then I was doing some leg exercises in the gym and my left knee clicked," he told The Sun.

"I instinctively felt it wasn't right and that I should probably go for a scan.

"I wasn't in any great pain. I'd played for Arsenal and we'd been winning, then for Scotland I got a goal and an assist. So there had been nothing to worry about after that Wolves match.

"But the scan result came back and suddenly I'm needing an op. It was so unfortunate. But after that click I just knew it wasn't normal.

"The verdict was 12 weeks — and it was gutting when I realised the games I'd miss for Arsenal and Scotland. However, there was nothing I could do about it."
