Like all fans, you have a select few that are morons. I can understand their frustration though, because it seems like this is largely due to Raiola's power. And it seems like he'll be getting ~2m out of the deal as well.
Anything to piss off that scumbag of a club makes me happy. I couldn't see Raiola letting Pogba go on loan next season to Siena or Bologna. He would own Marotta, not the other way around
