Kieran Tierney

Tierney signed a pre-contract with Celtic and will join the club this summer.

Tierney scored in his final game with Arsenal in the season finale against Southampton, a moment he had predicted himself in recent days, coach Mikel Arteta said in a press conference, praising the defender. "He said it yesterday, I'm going to score on my last Arsenal match and he's done it! So, credit to him, a special thank you to him. He's been part of the journey and he's won with me. It's true that he went to Sociedad for a few months, but it's been a joy to work with him, a really special character. We wish him and his family all the very best. The doors of this club are open for him - he's someone very, very liked at the club, in the dressing room and we want to wish him the best."

Tierney (hamstring) is on the bench for Tuesday's match against Sporting Lisbon.

Tierney (hamstring) is available for Tuesday's clash with Sporting, according to manager Mikel Arteta. "We have Kieran Tierney with us after a long injury. It's great news that he is back, he's been training with us and he is available to participate."

Tierney (hamstring) isn't available for Saturday's clash with Nottingham Forest, according to manager Mikel Arteta. "Kieran - not yet. He had a couple of sessions with the team but is not ready yet to be with the team, and Tomiyasu is going to be out as well for a bit."
