How to keep Messi through 2028? What's going on behind the scenes you think?

Genuine question - what can be done at the club level to keep Messi happy through the end of his contract at the end of 2028? Personally, I don't think he's sticking around after this season now that he hung up his boots for Argentina. I just don't see him dragging this out. Enjoy him while we can of course, but I'm wondering what Beckham et. al are planning to try and keep him around until the end of 2028. The void he's going to leave at Miami and MLS as a whole is going to be absolutely massive.

What's in the cards? A Neymar reunion? Other Argentina players? Not sure anything they do at this point will keep him, but I'm wondering what you all think is going on behind the scenes.
