Absolutely any team over level 15ish should think about selling off some people if not in CL or Cup, have a minimum squad to try to keep wages low, as well as playing friendlies rather than training when possible.

My League bonus was 875k forever, I hadn't changed it for like 10 seasons then a few seasons ago in a hard League I upped it... and REGRET. Nope, didn't help and that season I didn't promote so double whammy no CL or League money.
It won't go lower so I think next season they won't even get lunch money.

And I will continue to scour the TL for FA's under 25, though they are once in a blue moon.
