I have seen a speculation like this about Osimhen.

Could this really be true?

I mean is there really a chance that we can lose Osimhen in January? Because as far as I know he doesn't have a January clause and he is staying with Galatasaray until the end of the season.
I hope there isn't such option for him. Otherwise it would really be difficult to convince him to stay more than half a season. There will be an option to play in the Premier League on one hand in the end.
I wouldn't advice him to go to Manchester United despite the salary will be higher, the exposure will be there too and he'll be having better competitions in the premier league. Why I wouldn't advice him to switch clubs is as the Turkish league is the perfect league for him to build up his career again and get into form that he can use to negotiate a better payment structure for him at any club that wants to sign him. Him trying to get a new club in January will be desperate of him and the clubs interested will use that as a leverage on him to get a fair payment structure that will suit the club but not Victor Osimhen. He should stay with galatasary until the season ends.
