Scotland beat Denmark 1-0 on Tuesday night - and pundit Willie Miller has told BBC Sport that he felt Celtic's Kieran Tierney was 'very good'.
Gordon Strachan's men beat the Czech Republic 1-0 last week, and followed that up with another friendly victory as Matt Ritchie's goal won the game against Denmark.
With no Euro 2016 campaign for Scotland this summer, manager Strachan used the opportunity to give some young players a chance on the international stage.
Hibernian midfielder John McGinn impressed in his first start for Scotland, whilst Nottingham Forest teenager Oliver Burke came on as a second half substitute for his first cap.
Another youngster involved was Celtic left back Kieran Tierney, with the 18-year-old rewarded for a superb debut season in the Bhoys first-team setup.
The Isle of Man-born defender has supplanted Emilio Izaguirre in the Celtic side, and on Tuesday night, he started a Scotland game for the first time, before being substituted at half-time for his Bhoys team-mate Charlie Mulgrew.
After the game, former Scotland international and current pundit Willie Miller told BBC Sport that he felt Tierney was 'very good' in the first half, and has done his international chances 'a lot of good' with a sound performance, handing him a seven out of ten rating.
"The Celtic 18-year-old was very good in the early stages of his debut before Scotland started to get pinned back," said Miller. "He only played the first half because Gordon Strachan brought on Charlie Mulgrew for his extra height, but Tierney will have done his international future a lot of good," he added.
