Well, you have reached the boundaries of this limited game. They care about a solid basis who provides them good regular revenues. Managers on the top leagues of the server will always be marginal.

But think again, with so many pending issues and anomalies, why would they introduce something no one ever asked and no one really wants, and that is even dangerous?

The "take over" was the solution they found for the end of the rope managers, to make you go down.

One of their top priorities is the compulsory loss of quality that happens at the beginning of each level, which makes users regularly spend currency to keep up. But this poses problems like yours, so they introduced the take-over so that they can persuade the top level players to occupy vacant teams. Or else you'd just quit at some point because the game becomes absurd and paradoxical.
