The thing is that of the club knows their are going to lose their front man then a sure replacement need to be done on the player because that's the only way they can manage to meet up with the pressure that the league is going to provide, we can actually take Napoli for example these guys are out there in search for the perfect replacement for their striker osimien since he is bound certain to leave for either PSG or Chelsea.
Osimhen would have still been in Napoli but the challenge has always been that the club has not made the environment a very good one for him to play as he should and so it has now made him decide to even leave the team too aswell, replacing him now is on them and I think they will just have to look for that player that will better replace him. I believe this difficult has been one of the possible reasons they have made it really difficult for him to exit the team easily by increasing his bid.
