Kieran Tierney last played for Arsenal in August 2023 but the Scottish international defender is in contention to return to first-team action in the Champions League

A narrow 1-0 defeat at Inter Milan last time out has left Arteta’s side down in 12th place in the new-look Champions League table

Kieran Tierney is back from injury and available for Arsenal again, with the Scot travelling with the squad for the Champions League clash with Sporting on Tuesday. The 27-year-old has not played for the Gunners since the 2023 Community Shield when he came off the bench against Manchester City at Wembley.
