#1 Carlo Ancelotti
Having managed the likes of Parma, Juventus, AC Milan, PSG, Chelsea and Real Madrid, in Italy, Spain, France and England, a stint in Germany was the only missing thing in his illustrious CV.
Ancelotti appointed the manager of Bayern Munich in 2016, was to continue their domestic dominance and break the grip that the Spanish teams had in Europe. The club hasn't won the Champions League since 2013 and doing so wasn't easy.
Ancelotti has drawn praise for his adaptability, good tactical prowess and his calm, balanced approach as a manager. While his union with Bayern seemed perfect when he joined in 2016, the lack of silverware apart from the Bundesliga title in his first season put pressure on him to perform better the following season.
With multiple losses in the league and the Champions League, Ancelotti was sacked on 28 September 2017, due to creative differences. It was also reported that he had lost the dressing room.
