#6 Antonio Conte
Antonio Conte is an Italian manager who last managed Chelsea and helped them win the Premier League in his first season in charge, and the FA Cup the following year. He has previously managed Juventus as well where he won three consecutive Serie A trophies.
The Italian is a serial winner and he is known for winning league titles. His Juventus team still holds the record points won in Serie A in a single season.
Despite winning the Champions League three times in a row, the Los Blancos have been unable to replicate the same form in the La Liga. They are the most successful club in Spain, but they find it difficult to impose themselves domestically. But, in Conte, they can have a manager who knows how to win league titles and perform consistently.
The former Chelsea manager was linked with Real Madrid when Zinedine Zidane left, while he was also linked with the club when Juan Lopetuigi was sacked by the club. If things don't go well he is definitely an option Florentino Perez should consider. Also, he is currently unemployed which makes him an attractive option.
