Levein happy seeing Blackpool star Adam in Premiership
Levein was delighted to see the 24-year-old about to make the step up.
"Charlie, in the games I've seen him playing in since I took the Scotland job, has been Blackpool's best player," said Levein.
"I think that's widely recognised by the players and the management at the club.
"He has progressed enormously over the last year or so and he is now going to be playing on the biggest stage of all."
