Celtic defender Kieran Tierney has signed a new five-year contract that will keep him at the Parkhead club until the summer of 2021.
The 19-year-old left-back made a major impact last season - he was named PFA Scotland Young Player of the Year and earned his first Scotland cap against Denmark in March.
Tierney said: "Last year was my breakthrough season so I need to prove myself again and hold down my place. I'm obviously delighted to be here - my future is only here."
