#2 Massimiliano Allegri

The Italian is currently the manager of Juventus, where he has won four Serie A's consecutively and three Copa Italia's as well. Since Allegri's arrival in Turin, no team has managed to win anything in Italy.
He was also close to winning the Champions League with Juventus but the likes of FC Barcelona and Real Madrid have prevented him from doing so. His record with AC Milan was also fantastic.
Allegri is a great tactician and under him, the Los Blancos will have a manager who knows how to win trophies as well. According to reports, Allegri has already decided to leave Allianz Stadium next season and Madrid could be his next destination.
The Old Lady want to win the treble and they signed Cristiano Ronaldo for it. But they have been knocked out of the Copa Italia and a 2-0 defeat away to Atletico Madrid means that chances of progressing in the Champions League are slim for Juve.
