I have not known PSG as a club that will be hesitant to paying any reasonable amount of money for a player they want. PSG is not a small club and they have the money. This is evidence in their ability to keep three world class players in the same team for a good number of time (Messi, Neymar and Mbappé). The only thing that needs to be a kindled is the interest of PSG. If they are truly interested in Osimhen, they will get him and Osimhen will want to play in the Champions League over the conference league.
Most likely the process is being slowed down by Napoli, or they are demanding a completely unreasonable amount. PSG can pay as it seems to everyone any big sum, but no, there is a limit to everything. I think PSG will not soon be able to set a record for the amount of transfers, as it was with Neymar (until the standards of the modern market will not change and grow even more), so perhaps they began to spend less money on players, which is correct
