This irritating nature of some clubs to demand even more money and to complicate transfers seems to be unnecessary.
And that is the same thing that Napoli is doing regarding Victor Osimhen's transfer situation. Tiny details that could be compromised, but no the club refuses to. Right now, Napoli is requesting Galatasaray to pay the remaining €35m in 2026 instead of 2027 that they proposed and they are requesting a sell-on clause, which Galatasaray has bluntly refused. The hard work in this Osimhen's deal is excessive and there is a possibility that Napoli might frustrate Galatasaray out of this deal eventually.
