It has been suggested that Al Ahli made an offer to Messi, but it has not been clearly stated which club made the offer. It is stated that Ronaldo earns 185 million euros per year and will even have a minority stake in the club. This is an example of the huge financial opportunities that the SPL offers to attract global stars. Messi receiving a similar offer could be part of the SPL's strategy to increase its brand value. The SPL could be an option. However, the emotional appeal of Barcelona and the stability of Inter Miami are important factors that will influence his decision.
The Saudi Pro League has been known for their ability to offer players irresistible financial benefits to accept offers from their clubs but Messi seems to be more interested in staying put with Inter Miami. I believe Barcelona made a move for Messi last year but he wasn’t interested. AFAIK that talks are ongoing between Messi and Inter Miami to extend his contract with the club. I doubt we will see Messi and Ronaldo in the same league one last time.
