I'm paying some money; not a whale, but premium and monthly card, send premium as a gift and that's about it.
But I'm on level 6, so I just started to play the game, and already I'm getting sick of this problem here, so Nordeus, moderators etc... maybe it would be better to listen to people like Bruce Wayne and others a little more. Just a suggestion.

Because as I said, I'm on level 6, and already I'm not playing 2/3rd of the game, and I'm rapidly losing interest just beacuse of this issue.

Last season and this season I encountered exactly the same problem (and it is a problem, believe me) - cup and Champion league I forget at the same second I see 160% tanker in my group. No money from me there, not even clicking on games to see what's going on.
At the League it's O.K.
I have to really grapple and fight for first place, I don't mind it, some you win some lose, but when my association matches start to be the same... what to tell you?
It is a problem, and it shouldn't be on players to watch countless of hours of youtube videos and making hoops through some ridiculouss buying and selling players when the game should make a clean match-making system we're paying for, at the end of the day.

All the best.
