Yeah would be even more stupid than Coutinho and Dembele transfer as at least both were two of the best players in the world when signing them. Ney is probably not even best player in Brazil league.
With all his talent I genuinely think no footballer would agree to play the second fiddle to the greatest footballer of all time. Maybe some super loyal boy from our academy but foreign footballer to do that would be an extreme rarity. Hate towards him on that decision is not really justified. On top of that he left us for 222 milion. We could have built an even better squad if not for the board.
Eventually what will probably prevail is Flick's opinion on all this. If Flick would approve his comeback, there would be little to discuss. And he probably knows the best as well.
