For those who cannot make clear decision, on what to do, what to build.
I wanna state this:
* I have full 80k stadium.
* Against managerless teams I've played twice this season, once 57455 and the other time even 67115 spectators.
* This season my average is 71,143. The ticket cost is 100. I play few seasons about 7th ranked, by ratings 5-6th, by strength 3-6th seasons differs. Except the no name teams or friendly (extra income), my season average is over 71.000 per match

that's over 9M per week on average (full 16 weeks)
... and sadly, that is more, than I currently get from general sponsor this year

(I don't count winning bonuses)
FYI: the sponsorship from second half table I.1 team is lower..
I hope u've got the idea, what choice might be the best for u (o;
(the reason is size of the league, from my friends I know that other countries, do have way better offers)
~ feel free to comment, and yes, I couldn't pick up better than 3stars offer..
