The creative midfielder has moved to the Dons months after sealing a multi-million pound switch to Norwich from Coventry, where he returned on loan for the remainder of last season.
After two cup appearances for the Canaries, Alex Neil was keen to give him more experience and the 19-year-old opted to try something new in the Ladbrokes Premiership with Derek McInnes' team.
McInnes said: "He is very good technically, he can make the difference in a tight game and is someone who I really hope will enjoy himself here.
"He is a player who has had a lot expected of him from a young age. He has handled all of that.
"He got his move to Norwich at a young age and is someone who is very capable, very confident of his own work because he is a good footballer and he backs himself."
