i now ask for the weekly income of some mates of me(the same order like in your country but i won't translate them):
Spielergehälter: $ 200 085 Zuschauer: $ 198 845
Personalgehälter: $ 71 659 Werbung: $ 27 159
Scout - Ausgaben: $ 5 000 TV-Vertrag: $ 74 223
Total: $ 276 744 Total: $ 300 227
durchschnittliches wöchentliches Einkommen: $ 23 483
a strong third division Team(not superior), if you think that he can get 50k extra each week without putting lot more money into the rooster i think it is attractive.
A weak IIIrd division team:
Spielergehälter: $ 113 739 Zuschauer: $ 145 916
Personalgehälter: $ 53 349 Werbung: $ 31 156
Scout - Ausgaben: $ 10 000 TV-Vertrag: $ 74 706
Total: $ 177 088 Total: $ 251 778
durchschnittliches wöchentliches Einkommen: $ 74 690
50k are still a lot for him
One german 2 division team i know makes +50k a weak, so he could double up his income with cup.
But i think your income it more like mine:
Spielergehälter: $ 470 236 Zuschauer: $ 503 577
Personalgehälter: $ 74 971 Werbung: $ 110 003
Scout - Ausgaben: $ 5 000 TV-Vertrag: $ 141 255
Total: $ 550 207 Total: $ 754 835
durchschnittliches wöchentliches Einkommen: $ 204 628
and here the cup income is really less challenging, especially because i get the income of the home game around 570k if i win the league match before ... But in my league there are still 11 teams in cup, and three of them are eleminated in direct duells(playing with top lineups) and a fourth against a top team of the second league in a away match also playing with their first team - so i don't see that we don't take the cup seriously.
