Can someone please explain to me what's the sell-on clause that Napoli is requesting from Galatasaray to be paid in Osimhen's transfer fee? I am getting to hear about such manner of deal for the first time after you're requesting for a €75m as release clause. IMHO, this is Napoli just trying to make Victor Osimhen deal to Galatasaray a difficult one just to discourage the Turkish club in their interest for the Striker.
