Hey khris, thanks for the help!
I guess this is the screenshot you need. I was also saving players ratings after matches in an excel spredsheet. The lowest ratings average are 3-Pramono and 2-Román (6.9 and 7.0 respectively).
The strange is that these players were performing poorly only on League matches. This Christian FC suffered more trolls than me in this league - that's why I believe the source of the problem is the league, but maybe you don't agree. Cup and Champions League are totally fine. Anyway, I'll be glad to see what you think. Thanks!! and merry xmas!
