Aberdeen manager Derek McInnes hopes Lewis Ferguson and Ross McCrorie can follow team-mate Andrew Considine's example by being prepared to grasp their Scotland chance - if it comes.

Considine, 33, made his Scotland debut last month and the defender is in contention to go to next year's Euros.

Midfield duo Ferguson and McCrorie are part of the Scotland Under-21s squad.

"Once you are in you have just got to make sure you are ready, as Andy was," said McInnes.

"He gets in through somebody else's disappointment. It is the same for these boys - they have got to try and be as ready as they can be when the opportunity comes along.

"There are others ahead of them at the minute and while they don't need to necessarily accept that, they can see that, and they have got work to do get into the squad."

Former Pittodrie players Kenny McLean and Ryan Jack are among Scotland manager Steve Clarke's central midfield options for Wednesday's Nations League match in Israel (19:45 GMT kick-off).

"The squad has been pretty consistent," said McInnes, who won two Scotland caps as a player.

"It is difficult for anybody to get in but I think it is also unrealistic to think you are going to get through a full season, a demanding season, without injuries somewhere.

"Somebody's injury disappointment will be somebody's opportunity. I am sure there are players playing for various clubs, including our own, that will see the potential of maybe getting to those Euros - and what a carrot that is for them.

"Both players would deal with the games if they were called up, both have got a brilliant temperament, both have been key players."

Meanwhile, winger Niall McGinn will miss Aberdeen's next three games after picking up a calf injury on Northern Ireland duty.
