Please tone the offensive language down, I've had to redact a few words there.

The reason it seems 'unfair' to you in the Cup is that your team is a high quality for it's level.

Cup is seeded by average quality, so it's more of a challenge. It's difficult, but it can be done. I've regularly had Cup seeds 3 levels higher than me, and I've won it twice, take it from me that when you do win, It feels like more of an achievement.

You'll probably walk the League and CL with the team you have, and other players will probably see your team and feel it is unfair they have to play you.
