Imo last Juve coach that finished at an acceptable position in the league, but deservedly got the sack after losing the dressing room. Couldnt gain authority of neither the old guard, nor Ronaldo.
Also you need to understand that Allegri was sacked despite winning the scudetto and super cup and Sarri's last words to the Juve management: "You send me away, but this team is untrainable." Agnelli had lost the plot after removing marotta and giving paratici a promotion.
Only thing I'll give him credit for it being smart enough to realise he had to change his football to hang on for that scudetto. Some coaches cannot swallow their pride to change.
But he was the first of a set of bad decisions the club made in terms of staff and players. He wasn't a fit and he and the club knew the relationship was over halfway through the season, but everyone was professional enough to get the job done, and we had a good and experienced enough team to do it.
