Welcome to the Club, Mate ;-)
In my case it's not the first time, it happened often since level 8 (for me) began 10 days ago. But I am on 3 in league and might still have chances in the CL Group. But I doubt that now...
It is so intransparent. You don't even get warnings during the game which players do not perform, all statistics look bright and beautiful and then you get hammered?
This is nothing what I am willing to pay for. So for me free of charge from now on
