I have a CM Wilshere playing in CAM. He has 10 chemistry already, but still has a yellow circle below his card (i.e. telling me that he is slightly out of position). Since he has 10 chemistry is there any benefit to me using a position change on him to make him a CAM?
Applying a "CM >>> CAM" position change will cause the player to have full chemistry, but will not really show a noticeable change to his overall playing style. If you want to change this aspect, apply a playing style to the player and he'll then have better attributes in certain areas. For example, you could apply the "Hunter" playing style, increasing the player's pace. Hope this helps!
