I have seen a speculation like this about Osimhen.
Source: Goal.comCould 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.
