I have never heard about that. Do you know what reason there would be that those banks do not trust each other? Turkey isn't subject to any sanctions, are they? All these other transfers are no problem, why would this one be potentially a problem?
But I am sure this one is going through, if the issue is collateral to get this deal done, the will find someone who charges a nice fee for providing collateral and then the deal is done.
Not sure I'm not expert in the matters.
For sure Galatasaray is not used to do such big moves with big amount of money in multi year payment.
I'm not sure if is a problem with the club or the different banks, is too big for my understanding and research.
Farbrizio Romano said that Galatasary rejected Napoli new conditions.
Idk if this it the official news or the news they wanted to be out until the fix the bank situation.
