The Saudi League clubs are already thinking about bringing Lionel Messi and they are always ready to pay big money for Lionel Messi but Lionel Messi does not show interest every time due to which these deals are not being completed. Think for a moment if Messi comes to the Saudi League then we will be able to see the two biggest stars in the world of football in the same league and I believe if Lionel Messi comes to a club in the Saudi League then we will see many more players coming to the Saudi League then the Saudi League will become more attractive.
Lionel Messi is a GOAT and his playing style is very beautiful and entertaining so having him at any club and league is very good in general. Saudi Professional League under investment and strategies of PIF have wanted to build up their national league bigger and better. They have aimed at biggest star players like Ronaldo, Benzema, Neymar and several times tried to convince Messi joining their league.
It shows their big interests on Messi but there is a fact that times flies fast and Messi in 2025 is worse than messi in 2022 or 2023 by ageing effects. Saudi Professional League and clubs there will receive less contributing effects from Messi in 2025 than if they get him in previous years.
If the Saudi club wants Lionel Messi, it won't be literally on how productive he will be to the squad again but just to drag attention to the Saudi League just like Ronaldo did. The Saudi League signs European players just to game recognition as one of the developing leagues and not what those players will bring to the teams. Neymar Jr once signed for Al Hilal and didn't make any good performance but he was payed huge salary so i don't think they will expect much from Messi if they sign him to the Saudi League, his age wouldn't even be a problem because at Inter Miami Messi is still performing well.
