player perfomance

[Diegito]

o come on plz someone gives a simple answer to my simple question.
so finally , in this game,"perfomance" what will show in players stats after the game ends?
i think we all know the answer,even me who made that thread,but truth is so hard to face it...
and yes that game engine is very very annoying and confusing,i am in 5 season atm,lvl5,i have won
league,cup,CL but i still havent managed to UNDERSTAND how that game works!!!
seriously!!!
in many games i have won much better teams than mine but also in many games i havent managed to win
teams far worst than mine!!!
why????it was only luck???
whats the point of player quality?whats the point of formations,tactics?
why a 1* player performs better than a 5* player in that game?
plz NORDEUS give as an answer!!!
