Former Celtic boss Gordon Strachan has no doubts about the potential of Arsenal fullback Kieran Tierney.

On Saturday, the young Arsenal defender can add an FA Cup final to a list of professional achievements that already includes 12 caps for his country and four Scottish titles.

Strachan told the Daily Mail: "He has the type of mind that allows him to think that whatever he tries will come off. He has complete faith in himself and it's totally justified.

"I played him at three positions for Scotland. Left back, left of three centre backs and also right back.

"My two best players were left backs — Kieran and Andy Robertson — so I shifted Kieran across. He never complained. He just got on with it. That's how good he is and that's how good his attitude is."
