He even said in that press conference himself that he will essentially die on this hill playing the football he wants as it has "worked my entire career" but then he also said himself "but the premier league might be too big of a jump, who knows mate."
If he requires Levy to gut the team and rebuild it for this style to work I think he might be in for a shock tbh.
Like I said before, Levy wouldn't back Poch after a CL final, Conte or Jose with rebuilds; what makes Ange believe he will get backed? Especially after recent form?
I think you're worrying too much
