Really nobody know's how are the hidden abilities proggrammed in players, % by default of effectiveness, in what % affect the morale, in what % affect the low condition, in what % the wrong position, in what % the bonus, in what.... in what a lot of thing's and the "match scenario's" or "types of matches" or, "circumstances" that the game use to do the matches simulations, and bring the matches to one way, maybe, this match your team is more aggressive, maybe, you win 1-0 and the other have 5 yellow cards, nobody know really that.

That's why I try to play that trying to understand how is programmed this thing...

this thing...
