a good manager (football manager or otherwise) is one who gets the job done in spite of circumstances. That's when he / we really earn the money. This manager is not going to get to build his own squad because he's not showing sufficient competence to continue - he's shot through.
Luckily for you you'll never be proven wrong, emp; you'll always be able to say 'he never got a chance' despite the fact he's never earned it.
