Changing coach if we win CL would be absolutely retarded, unless Allegri himself has decided to move on. This really isn’t up for debate. You would have to be completely retarded to advocate firing him after winning CL, given the 5 years we have had.
And

that changing our coach would double our appeal. Yeah, show some evidence for this claim please.
