Miller was absent from Motherwell's recent match against Rangers, citing injury as the reason. However, it appears that he was actually involved in negotiations with Torino at that time.
Miller had a successful season with Motherwell, earning the title of Young Player of the Year in the Premiership. He scored four goals and provided six assists in 34 appearances.
If the deal goes through, Miller will join his Scotland teammate Che Adams at Torino, who made the move from Southampton last year.
