Steve Clarke admits he left Billy Gilmour out of the Scotland squad to allow him to develop in Scot Gemmill's under-21s outfit,

The Chelsea kid, 18, has already forced his way into the Chelsea first-team set-up and was widely touted for a call-up to the Scotland proper squad.

But the Scots boss has urged Gilmour to continue his rapid rise to the top without any added pressure.

Lawrence Shankland and John Fleck confirmed in Steve Clarke's Scotland squad for Euro 2020 double-header

He said: "Billy is an exceptional young talent and we have to give the young players time to grow and develop.

"The best place for that is in Scot’s under-21s team and he has been in tremendous form.

"It’s the same with Mikey Johnstone who I considered calling up. 

"There’s Fraser Hornby and a good few others too.

"If they can continue to develop together then that will be good for the future."
