Duje Caleta-Car has a strange deal.
From an online article:
On Wednesday, it was announced that Lyon had signed Duje Caleta-Car from Southampton, but it wasn’t the deal everyone was expecting.
It’s explained that Lyon paid Southampton €1.54m up front for the loan, which will be used by the English club to pay Caleta-Car’s wages. Therefore, no new salary appears on Lyon’s yearly bill.
