Of the uncapped players, Miller undoubtedly has the most hype around him.

Motherwell’s 18-year-old midfielder has improved at a remarkable rate since making his senior club debut aged just 16.

He won the PFA Scotland young player of the year award last month after a season in which he scored four goals and assisted seven in 36 games.

Miller is expected to leave Fir Park for a sizeable transfer fee, one which could be bolstered should he make his Scotland bow against Iceland or Liechtenstein.

“I could maybe, in a couple of months, be the best player there,” Miller said after his first Scotland call-up in March.

He later clarified his comments, saying the speed of that claim was a “mistake”, but reiterating his desire to be the best player he possibly can be.

Short of confidence, he is not.

Bowie is another who will fancy making an impact, should the opportunity arise.

Quick, strong and imposing, he scored six goals in his first season for Hibs after recovering from a hamstring injury sustained playing for Scotland Under-21s.

“Any time I watched the Under-21s he always stood out,” Clarke said when naming his squad. “He’s big, physical and strong – with good attributes to his game.

“Going into the summer, you’ve got Lawrence Shankland and Kevin Nisbet, I know what they can bring, so it was just to have a look at something a little bit different and see if we can expand the pool of players.

“You’re looking for somebody to catch your eye.”
