I think everyone thinks that if they can understand the randomness, they can improve their team and ensure that they win more. Unfortunately, from my experience, it seems like some games are just scheduled for you to lose. I have noticed that if you win big in previous cup matches and champions league games, you inevitably get trolled. The complaint here, of course, is that you become powerless to actually do anything. The opponent has one midfielder and you have 3, but that is irrelevant, the opponent still dominates the field. The opponent has no tactics, it doesn't matter, your prove tactics are ineffective. Ultimately, there is a part of randomness in the game, which isn't bad in and of itself. However, when it makes much stronger teams lose inexplicably, then you know that the game is rubbish.
