If we're gonna get a new coach then it MUST be a proven one. I know that sometimes teams took a risk with an unproven coach and won a lot (Ancelotti in Milan, Lippi in Juve etc) but we aren't in position to take a risk.
We have a good team, good players, but we aren't world beaters and we can't allow someone like, lets say, Bilic make experiments here.
We need a winner. If
the winner is currently earning 5m euro, then offer him 7 or 8m and make him leave the team he's coaching.
But do not take a risk with Conte, Ferrara, Gentile and the likes.
