The team he inherited at Milan was star studded and only 3 years earlier had won the Champions League. And that particular squad was considered the best in Serie A. Robinho was displaying fantastic form and was flying at the time for Milan. Allegri won the the league with the best squad in the league in his first season. His second season he lost the league to a inferior Juventus and his final season was so bad that many fans called him clueless and the football was absolutely dire. How he got the Juve gig after his shit show in his last two seasons at Milan was truly baffling and many Juventini were extremely dissapointed with his appointment at the time. There's many parallels to be drawn with Allegri's time at Milan and Mourinho's at United. Only difference being Allegri inherited a much stronger squad in comparison.When Allegri took over AC Milan were a cup team which was already in decline. They haven't won the league since 2003-2004, Ancelotti left in very bad terms and it was evident that the AC Milan of the past (ie who invested heavily on the squad was over). Allegri took a rather ageing squad which was strengthened by loaned players (Ibra), rejects (Robinho) and bad boy, Cassano. He also had Pato who had the injury record of our Jones with the difference that Pato was screwing Berlusconi's daughter which basically made him untouchable.
Allegri took this mismatched squad of giant egos and an ageing squad of players who gave their all to Milan and were in no mood to accommodate divas to a Serie A title success. After that Berlusconi kept pushing players out. Pirlo left in 2011, Ibra, Thiago Silva, Van Bommel, Aquilani, Cassano and the old guard (Gattuso, Seedorf, Nesta) left a year after, then it was Boateng and Cristante time to leave. AC Milan barely had any decent players to rely upon anymore and things spiralled out of control.
I can't see how you can possibly blame him of what happened at AC Milan and you certainly don't get Juve's top job unless you did something right.
Regarding pirlo he said
'There were problems with Allegri at Milan, because I was injured for four months of that year," Pirlo said - via Football Italia. "I returned when the team was doing well and it was difficult for him to change formation at that point too. Milan had won the Scudetto.'
You can't blame it on that either
Would be a bad appointment and we'd fall further behind the pace setters because both Klopp and Guardiola are far superior coaches. At least with Nagelsmann and Rose we'd have two coaches who have the potential to bang with the best.
