Aberdeen manager Craig Brown is expecting Fraser Fyvie to move to England next year.
The 18-year-old, who has made more than 50 first-team appearances despite a cruciate ligament injury disrupting his progress, has told Brown he will not extend his contract after rejecting an initial offer.
Fyvie's current deal expires in December and Brown expects he will sign a pre-contract this summer with a view to move south of the border next January.
"At no time has Fraser Fyvie mentioned money but he has said he would like to pursue his career in England," he said.
"He has been honest about it and I don't think he would be disposed to stay in Scotland.
"I respect what he says - he wants to play at the highest level and that is in England.
"He is very single-minded and, although I think he is a bit premature going before he has established himself, that is my opinion, that doesn't matter to him.
"I predict he'll sign a pre-contract in the summer and will leave in December.
"He's had a hard time, Fyvie, and if I were his agent, I would say wait a little while longer.
"But young lads nowadays want to be superstars early, and he might well be. That's his decision and we've just got to accept it."
The news will be a blow to Aberdeen, who only last month last teenage talent Jack Grimmer to Fulham.
