Over Bank Limit

If i'm currently over my bank limit, will my championship bonus still be added?
Yep should be. Don't reduce your own bid on any items at the start of the season though or any over limit won't get refunded to you.
Yes you can. I sometimes try to fill my bank limit in football champions so that i get my bonus filled and upgrade my stadium when i don't have enough money for the stadium upgrade otherwise lmao
