Top 10 managers of the decade

7. Massimiliano Allegri

Allegri did a 3peat of the Italian double with Juventus

Teams managed this decade - AC Milan, Juventus

One of the most versatile and tactically adept managers of this generation, Massimiliano Allegri makes this list due to his impressive work in Italy over the past decade.

Allegri started off this decade with Italian heavyweights AC Milan, who he joined in 2010 after an impressive spell at Sassuolo and Cagliari. In his debut season with Milan, the former Italian international surpassed all expectations as he won the Serie A, the first time that the club had won the trophy since 2004. He defeated neighbours Inter in both the league games that season, becoming the second-youngest manager to achieve that feat. He beat Inter again to secure the Italian Super Cup next season.

Allegri departed from Milan to join Juventus in the summer of 2014. In his debut season there, he won the Scudetto with the Old Lady and lead them to the finals of the UEFA Champions League, their first appearance in the finals since 2003. They lost the finals to Barcelona, but Allegri's tactics and the fluidity of his team were applauded by fans and experts around the world.

The former Milan manager did the double with Juventus three years in a row, and in the process, Juventus became the only team to 3peat the Coppa Italia trophy. A four-time winner of the Panchina d'Oro (an award handed to the best manager in Italy for a particular season), Allegri has been the best Serie A coach of the decade.

The manager has said that he intends to retire at the age of 55 due to the load of his job, and he is 52 right now. There is no doubt that Allegri is the best free-agent coach in the market at the moment, and wherever he goes, that team will have gained a gem of a manager.
