But that's my point, it's not the only criteria bu it's a big one particularly when there is no mid to long term alternatives or someone that would definitely outperform the likes of Conte, Tuchel, Guardiola, Klopp or even Moyes. And there is no way, that you(NK86) wouldn't take into account the timing of the contract extension when you think about sacking the manager, we need to be consistent and realistic here. It's neither greed nor incompetence, it would make no sense to sack him without thinking about it and giving him more time than you would in a different context, that's how Benitez lasted until January for Madrid. The only reason you say that is because your words have no consequences.
And I will reiterate my overarching point, the extension and the lack of quality mid term manager means that the club will logically need more time to pull the trigger, as long as things aren't toxic behind the scene. It's frustrating for us, the fans, but the extensions were always going to create that scenario unless the board is made of lunatics like Zamperini.
