I agree, but I’d like to add that though Maresca often referred as a guardiola pupil (ultimately Cruyff), where each player doesn’t have a truly fixed position, both Maresca and Ranieri come from Italian Football, which is reliant on a “regista” or a dominant center fielder. Once Kante was gone Ranieri would have, and he did, had a difficult time executing his system. So no the destroyers were the main officers who couldn’t find a proper replacement.
