Martin Keown hailed Kieran Tierney as a future Arsenal captain after his influential displays in the Premier League.
The Gunners legend also revealed team-mates have to tell the left-back to 'calm down' in training because he tackles too hard.
The Scottish international, 23, has been a rare positive in a difficult season for the north London outfit, and was one of the best performers as they made it three successive wins in the Premier League with a comprehensive 4-0 defeat of West Brom.
Arsenal have been criticised for having a lack of leaders in their team, but Keown believes the former Celtic man may possess the qualities needed to wear the armband.
