I agree with you. With Manchester United's current financial situation I think bringing in Osimhen would be very risky. In fact many fans seem to agree that Osimhen should join United because they need a great finisher. But so far United have tried to bring in many players with fantastic prices but in reality they still can't make a significant contribution to United. Manchester United can bring in Osimhen by selling some of their players. But can they do a deal with Napoli? There are reports that Napoli want a price of 75 million euros. That is not a difficult price for Manchester United if they sell some of their players. However I doubt it because it seems that United's problems are more complex although I agree with the fact they still need a complete striker with good finishing ability.
Manchester United has a lot of players in its squad. Manchester United pays high wages to its players. But even then, the performance of this team is weak. Manchester United has changed coaches several times in the last few seasons, but we do not see the expected performance from this team. So now Manchester United should reorganize the squad.
Since Manchester United has a lot of players in its squad, the United management will have to sell some players. However, United will not be able to sell the players at a high price. Even then, they can reduce the overall cost of the club a little by selling the players. And gradually Manchester United will have to try to re-form the squad.
