I just want to know if a player can change his prefered role during a game? My assistant tells me that Fellaini is best when played as an anchorman, but if I constantly play him as a deeplying playmaker, will he then eventually change his preferred role to the latter? Or if I buy a youngster who is best suited as a right winger, when played as a trequartista, will he then after some time be able to change his preferred role?
