Interest from Al Nassr had already been established as they had already submitted an offer to Ronaldo's agent Jorge Mendes. Over the duration of that contract offer, Ronaldo would have played past his 40th birthday, the veteran would earn £172.9million per year - an amount that would not be feasible for any European or MLS clubs interested in a move for the striker, split between his playing contract and marketing obligations.If that deal comes to pass, Ronaldo would not only become the highest-paid footballer of all time but would come close to doubling the current highest-earning star – Kylian Mbappe.
