Well the previous season I was level 3 and was placed among lvl 4 opponents in the Cup .(my team was Q 28 at that moment ) . Though these tough competition I managed to win it and it gave about 10 million $ ( approximately ) to my budget.

Near the end of that season I sold some players and quality dropped to 26.5 , this time I was placed with opponents of my level (level 4 now )with similar quality, but now I notice the potential income for the whole tournament (till the win on final ) is about 6 million $. (Ex for the final match it gives 843 k$ , but in the last season it was 1.25 m$) .
So the income depends on how tough your opponents are ?
