#3 Roberto Mancini
The current Italy manager spent three and a half seasons with the Manchester City side and led them to their first league title since 1968, in the 2011-12 season.
Mancini won the Serie A, first as a player with Sampdoria and then as a manager with Inter Milan. During his four-year stint, Inter became not only a dominant force in Italy but in the European football too.
After a fruitful spell as a manager in Serie A, he joined City, in December 2009. And since 2010, under him City had qualified for Champions League in all the season he was in charge.
He managed to win almost all the major trophies English football has to offer with City, the League title, FA Cup and the Community Shield too.
So, he was one of the best Italian managers of the Premier League era for sure.
