Yep i think that is probably the reason as well, if he changes it and things dont go according to plan he will be afraid of the backlash, but surely as a coach u should play the philosophy that has worked for u in the passed and not just copy what the previous coach done? Any formation could win us the league in Serie A as our players are just siperior to the other teams so why not take some risks?
Dont ask me why.
I think thats the difference between seasoned top coaches and average ones, specially if they are italian with italian mentality.
Coaches like mourinho , bielsa, carletto etc would have enought guts to change things if they believe they could work in certain way.
Maybe allegri sees this as a unique opportunity to continue coaching a top club and wants to play it safe, using something that has high chances of giving silverware in italy.
The question is.... winning the scudetto and crashing tempestously from the CL would secure his spot?. I pretty much doubt so. He was assigned as Juventus coach uner special circumstances.
The board already said that doing good in the CL was a must. The problem here would be if they want allegri to do that with the Conte plan. if this is the case, then the cards already have been thrown.
