#2 Massimiliano Allegri (Juventus)
He is one of the most decorated managers of recent times.
After leaving from AC Milan, he was appointed as the manager of Juventus in 2014. Since then, Juventus has won the league and Coppa Italia for 4 successive years, whilst reaching the Champions League finals twice.
His tactical know-how is unparalleled and is widely regarded as one of the best coaches working currently.
Allegri is someone who blends in with the club's situation. This is evident by his awareness to continue with Conte's approach and gradually make changes as the season progressed. He is someone who brings in a lot of stability and calmness to the club, which is exactly what United needs right now.
He has achieved almost everything with Juventus and the only blemish is a Champions League winners medal. Everyone expects him to go all out for it this time around, with Ronaldo in the side. It might be time for him to take on a new challenge after this season at Serie A and Manchester United would be the perfect destination.
