two lvs above is still too high. Imagine that if that team has some 6* players, they are 8* for you.In a way that no matter how much you dropped your quality, you would never meet managers more than two levels below you?
1 level above is more fair
* I can say here (from my experience in the Cup/ played a lot of games) that a 6* team of a manager 1 level above you, is much more difficult from a 6* team of a manager 2 lvs above. The second, is a 4* team for the manager, meaning that he is not interest much for his team, not very active, not enough sources (condition/morale of the players).
Also want to say that t11 it's just a game based on football but there are many differences from real football.
