Sometimes young players perfome bad in first season.
GK only have good rating If they makes saves, whend they does not have nothing o do they have bad ratings, MCs also have a lot of bad ratings.
I have a ML/AML that most of the time gets 7, even one time that he got 3 goals, on another score 4 goals, got a 8 and wasent MOM.
I stoped looking at ratings, they simple do not make sense.
