both coaches contributed a lot and improved us to an extremely high level. Conte made this team, he set the foundation, inserted the right mentality and made the team win again after a long time. once he felt he reached his limit here, got exhausted mentaly and didnt feel the same hunger for success as previous 3 years, he left. how he left is another story but no one can take away what he did for us in those 3 years. Allegri took over his team and improved it further tactically and technically, which made us one of the top teams in Europe again. both coaches were here at the right time and gave us exactly what we needed in their time here, ofcourse with Marotta as the mastermind behind all this. if we got Allegri 1st and then Conte, who knows how we would look today. maybe both would fail, or only one of them. but the way it played out worked great for us and thats all that matters really
