When you look at a staff member in your inbox, this shows you three stats below their name which the game considers to be core abilities for that staff role. In the case of Assistant Manager I believe that is Adaptability, Discipline and Motivation.
Personally, firstly I make sure they have good Motivation as a ask him to do team talks now and again. I then make sure his coaching style and playing style suit my own, because Ive come to believe this will effect his media interviews. I look for an assistant manager who likes a level of attacking football, as this transfers to the reserves when I ask him to manage them, and to my players if I ever have to sit out or ask his opinion on tactics.
Asside from these, I look for a reasonable stat in Determination, Discipline and Motivation because these are the core mental stats which boost his coaching ability.
