Choices of the past influence now. That is always in BB.
Three seasons ago I got relegated, due to many injuries that season. I went all in, but at the end, I relegated and had to sell my top players to adjust to the new league and not go bankrupt.
I re-build my team it took me 2 seasons to find players and to promote and now I have a relative young, cheap team, I make tons of money and it looks like I have a future.
If your team is going no where, than sell some parts. Take your time to find players that fit your team and fit the future. Maybe you relegate, maybe you stay, but at least you have built something for the future.
Only in the dark, we succeed!
