One team keeps 'changing'

I've noticed in my league that one team keeps changing managers every 1-3 days.
It's always a different person taking over.

Each time a new takes over, the scores for the old team remain as if the new team achieved the scores.
If you click on a previous match, the stats refuse to show up.
Early on, this team actually beat mine 5-1, but then it was replaced by another team.

Is there a reason why a manager is dropping out?
I can only think that maybe they ran out of in-game money?
