chelsea vs southend 08/09 fa cup at the bridge

i just dont see de zerbi as the pep replacement people think he is, any other club recruits a new manager and there’s talk about how there’s no trophies in his cabinet etc, de zerbi has done a good job at Brighton and a good job before that but how can you replace pep with someone who hasn’t really won any major honours(or replace him at all for that matter)?
