“I hope he keeps going the way he is going as he has a big career in front of him.
“I know how he will be feeling right now. I’ve been there, coming through to the Scotland squad at a young age.
“We are in different squads this time, but I am sure I will be able to help him in the future. It’s good to have someone who has come through similar circumstances. I’m still young and trying to learn and improve my game.
“I’ve played a few times on the international stage, so maybe I can pass a few things onto him.
“We’re fighting for the same position, but that’s great. The more good players competing for places, the better for Scotland.”
