I seriously doubt that Victor Osimhen will be going to Manchester United. To me, it’s fake news. There’s no logical reason why Osimhen would want to go to the place where careers die. Maybe Manchester United was boyhood fan club but that is not enough reason to end a very promising career. If Osimhen moves to Manchester United, be assured that he will tagged as the problem when things are going bad for the club.
If he is paid handsomely, then why wouldn't he go? Plus, United plays in many cups already, and winning just one of them would be a great achievement for both Osimhen (to make the team better by joining) and for United as well. If he is paid lets say 20 million, it would be more than he is being paid right now and also it means he will be playing for a team that used to be great and needs to get better again. If he joins Manchester United, and they win either EFL or FA cup, which isn't impossible, then he could be increasing his stock value there too. Then they could just go to European competitions again.
Amorim never had a summer of his own so far, so with this summer, if Osimhen joins, there will be some more moves, and expectation is that they will finish better next season.
