Doesn't mean the jobs they wanted would've been there - if De Zerbi wanted his own new GK coach and striking coach (likely), he'd get them.
It still would've been a very risky for them financially. There isn't an endless supply of well-paid jobs at the club.
Do we know this for a fact? I thought they were told there was a decent chance De Zerbi/the incoming manager would want to bring his own men with him, as is pretty much always the case at this level.
