So far Lionel Messi is still reluctant to answer how his fate at Paris Saint Germain, stay or leave. It seems he wants to focus first on defending his country in the World Cup. I haven't heard where he would have joined had he not decided to extend his contract with Paris Saint Germain and it is very possible he would return to the team he came from and also make his name big, Barcelona. But it looks like Paris Saint Germain will try everything they can to keep Lionel Messi with them.
@Furious 7, It seems to me that Messi is not interested in having such a small competition. His competitive nature makes him a very effective player. It does not matter how old he is, he is still a competitive person, even if he is already almost 34 years old.
You know, he barely has any competitions at PSG. In addition, things have gotten very toxic at PSG, especially since Mbappe has been given so much power by the club. I don't think he liked that at all. The fact that he doesn't want to stay at PSG makes perfect sense if that is the case.
In spite of this, as you said, money has the power to change everything. In addition, I would like to point out that Neymar is one of his most reliable close friends. Probably he might tell Messi to stay at PSG as well. I think at this age PSG is appropriate for Messi.
Most likely, Messi will leave PSG after his contract expires in 2023. even if there is encouragement from his team-mate, Neymar, to extend his contract with PSG.
some of the points you said, are the reasons he is reluctant to continue his contract with PSG. especially the little boss "Mbappe" who has privileges over other players. when it comes to salary, I'm sure Messi doesn't care too much about it, although it's fantastic. he, had everything. however, what he wants is the comfort of playing with the team and winning as many trophies as possible at the end of his career.
Neymar has a new long-term contract with PSG, as well as Mbappe.
but the loss of Messi could be a problem for PSG, not in Ligue 1, after all they are too strong in the francis league. but for the Champions League, it is clearly a problem for Galtier's team. and because of that, SPG are looking for options to replace Messi later.
