Napoli president Aurelio de Laurentiis says selling Victor Osimhen will be more emotional than financial.
Osimhen could leave for a fee as high as 150m this summer.
De Laurentiis said at the FT's Football Business Summit: Osimhen has a release clause. That's a lot of money. Money is Napoli's latest problem.
"We have always made good purchases and will continue to do so in the future.
"The problem is only sentimental, because every time a player leaves it's like saying goodbye to a child, but at the same time you're happy even when he achieves success elsewhere."
