SCOTLAND captain Darren Fletcher will urge the newcomers to seize their international chance ahead of tonight's friendly in Luxembourg.
Caretaker manager Billy Stark has called up several players for the first time after nine call-offs from his original squad.
Hibernian striker Leigh Griffiths, Inverness midfielder Andrew Shinnie and Kilmarnock midfielder Liam Kelly all won first call-ups on Sunday.
St Johnstone midfielder Murray Davidson is also in line for his international debut.
Fletcher won his first cap aged 19 and captained his country aged 20, so he knows an encouraging word will go down well.
The Manchester United midfielder said: "Hopefully I'll have a few words with them before the game and just try to reassure them that they deserve to be here.
"They are Scottish internationals and (they should) really embrace that, express themselves and take their league form into the international scene."
