At this point, we have to be fucking honest.
This is not "tevez we got for a peanut and was amazing but said from the start he was gonna go to boca" scenario. (he didnt had to go a year sooner tho).
This is Pogba, who is young as fuck, who has 4rich clubs that want to sign him, and never before made clear he wanted to join a certain team.
Pogba was a fine player, we dont really "owe" anything to. While he was injured, we kept trashing serie a and made it to the CL final.
This is pure business. He cant pull this shit of "only barcelona", cause fuck him very much if he does. Who the fuck does he think he would be ? He got a big raise. He wants to leave ? Good, fuck off, to the highest bidder or stay
He has a 5 year contract, what is he gonna do, rek his career ?
