I can agree with everything u wrote in this thread.
I'll tell you what I speculate. I have a team which is about 108% at the moment.
On my league, I feel they are playing like a 50-60% team. I just can't beat opponents stronger than that, even that I give 300 shots on target and my opponent does only 1. The background is that I have won the league last 3 seasons.
On Champions League, my team is playing great. I have a group with 4 teams above 105% and I lead with 3 wins, 1 draw. The background is that last season I was eliminated on quarter-finals.
On cup, I'm still going through it. But I have reasons to believe I will have some sort of shame elimination, cause last season I won the cup.
This sunday, I had a draw against a 54% opponent (inactive). Even that my changes during the match affects the results, it's like the system is "putting factors" to make my team lose. It's just horrible.
