Master League Focus Points

[Jamesmazon]

I was wondering if anybody knows which skills each focus point is related too. LIke there are 6 areas we can choose a player to train: Shoot, Pass, dribbling, defence, athletic ability and goal keeper.
I´ve done some experiments and it seems balance for example is affected by focusing on defence and athletic ability. Does anybody have a chart or something like that, explaining how does it work?
