His team could have gone bankrupt and the whole team was put on sale because they couldn't cover his debt.
23 days old, 12 days without connections. I doubt he was in debt.
He surely fired all his players then leave the game. He will botifie in four weeks, since then all his games will be walkover.
I'm not so sure about that. He might be somebody that knows the game from previously and he fired all his players to maximise his income (no salary floor for new users). Then he'll build a team for season 22 in the off-season.
