I will repeat myself: if any big club was really interested in Oshimen, they would have paid Napoli any amount of money a long time ago. Look at how much money many big clubs are spending in this window on other players, this is a clear sign that they have no interest in Oshimen.
We can't speculate on why a transfer hasn't gone through cause we do not have insider information. With the talent
Osimhen has and the number of teams looking for a good striker, it's a no brained that he should have a deal. We have to wait till the end of the transfer window to know what happens.
In my opinion, Oshimen should be very grateful to Galatasaray, because at least they are the only European club in the Champions League interested in him. If he fantasizes or deludes himself into thinking that other big clubs will come and sign him, then he will end up in the Saudi league.
It's a mutually beneficial situation for both. With the amount Galatasaray paid to get him and his salary, lots of teams in the Champions League will grab that offer quickly.
One of the best strikers in Europe shouldn't delude himself?
