Did anyone not see this coming ?
Harry did his usual, spend all the clubs money. Leave when the bills the have to be paid.
I don't understand how you can blame the manager for that. The manager will spend anything he can get on strengthening the team, which is perfectly understandable as there is always room for improvement. If Levy (or whoever is in control of the finances) has let him spend more than they have available then that is not Harry's fault.
