In all seriousness it'd never happen, but I think the Caf would spontaneously combust if it did. Hard to say who could come in and be of the required quality. Barca's three are ungettable (and unwanted in Bitey's case), Real wouldn't sell any of theirs, of the Bayern forwards only Muller jumps out as an ideal candidate but would likely command a fee in excess of that we paid for AdM, Ibrahimovic is too old, Aguero is basically ungettable and perenially injured, Higuain and Cavani are not good enough imo, the likes of Lacazette are exciting but not at world class level yet (though wouldn't mind him nonetheless).
I wonder what the club is planning, I really do.
