Former Scotland striker Steven Thompson believes we already witnessed who will fill Tierney’s boots when Scotland walk on to the pitch in Stuttgart on Sunday.

I think what will happen is Scott McKenna would just come in.

He’s a decent replacement and is a very good player. He offers us an aerial threat in both boxes for set plays.

I doubt the manager would deviate from the shape he plays and McKenna will just slot in.

It’s obviously a major blow with Tierney going out, he’s one of our best players. His combinations on the left with Robertson have been a big feature for the national team under Clarke.

You have to feel for him. He’s had an a horrendous time with injuries. It’s absolutely devastating for him.

It’s a once-in-a-lifetime opportunity and, now his tournament is over, it’s 10 times worse. Especially now they’ve got the opportunity to be the first Scottish team in history to get out of a group if we get the result we’re desperately after.

But the team has to kick on and react.

They’ve had a lot of adversity to deal with in terms of injuries, plus the red card for Ryan Porteous in the first game against Germany was a curve ball.

But they can’t afford to think about that. Ultimately, there’s a job to do.
