#2 Antonio Conte
Antonio Conte is the one who brought the glory back to Juventus during his tenure at the 'Old Lady' from 2011-2014, and also revolutionised the game with his 3-5-2 formation. He also started his Premier League campaign by lifting the title in his first season with Chelsea. Many believe him to be a suitable replacement for Mourinho.
Conte has his own style of playing football, with three rock-solid defenders along with two wide wingers who could support the running midfielders and strikers. This formation led him to three consecutive titles with Juventus, and the same formation made him famous at Stamford Bridge where he won the title in his first season.
Conte is also familiar with the Premier League, and his style of football was praised. He can provide United with more stability at the back, as they have already conceded lots of goals this season.
Manchester United desperately need some reform in defence, and the Italian could be the one to take them out of their defensive miseries.
