Boss Craig Levein has backed Peterborough striker Craig Mackail-Smith to be a hit with Scotland after his surprise call-up.
Mackail-Smith has been drafted into the squad ahead of Sunday's friendly against Brazil at the Emirates.
The Watford-born forward is eligible thanks to his Scottish grandmother and has impressed Levein with his 27 goals for the Posh so far this season.
The Scotland boss said: "Craig is a player Michael [Oliver, scout] has watched for some time and he has been highly recommended to us by Darren Ferguson. He has had a fantastic season and I am confident he will be able to translate his domestic form into the international arena."
Uncapped Mackail-Smith is now determined to prove to the Tartan Army that he is good enough for Scotland.
He said: "I knew the Scotland scout had been watching me this past year and I am delighted it has come to fruition. Hopefully I will get a chance to show the Scotland fans what I am capable of."
