I completely get you. When it comes to Enrique, I’m all for him. The two things for me concerning De Zerbi in relation to the points you bring up are:
1. I think De Zerbi is different to EtH and Amorim in that he’s proven he can get multiple teams playing his way consistently for around a decade now. All of his teams have played his style regardless of the quality available to him. The way his teams set out to play has remained consistent; It’s just, the better players he’s had, the more effective his style. It’s not like EtH who only played the Ajax style because he had to there, and reverted to his chaotic style elsewhere, or Amorim who was still relatively unproven. If he joins, even if he’s not a success in terms of trophies, I think he’ll elevate our play in general.
2. This is just me but I think, long term, it'd be more beneficial for us to get in someone who will completely revitalise our style of play so that we give future managers the best platform to succeed from. Enrique seems like he could do this but is unlikely to join. The next best option, to me, is De Zerbi. You, rightly, say players will want to play under the managers you mention, but I think players would want to play under him here, too, because his proactive approach is a style I think most players would love to play.
I could be wrong so feel free to correct me but I think the majority of our better chances come from transitions. When we're facing a deep defence, we still struggle to break teams down because we lack the technical players to play in tight and congested spaces. Only Amad really thrives in that area.
