Galatasaray committed to a flat $87 million fee, nearly four times the previous biggest fee paid by a Turkish club ( Youssef En-Nesyri 's move to Fenerbahce in July of last year). Including loyalty bonuses and image rights payments, Osimhen earns nearly $25 million a year and Erdogan's extremely hospitable tax arrangements for international footballers (a flat 20% income tax) means he takes home an awful lot of that. They didn't stop there either. The three most expensive signings in Super Lig history were made by Galatasaray in the last five weeks as Wilfried Singo arrived from Monaco and, on deadline day, they swooped in to end Türkiye international Ugurcan Cakir 's 13 year stint at Trabzonspor, the most successful club from outside Istanbul.
