I think what Messi has achieved with Inter Miami is remarkable,some may say that this league is easier than the European Leagues he used to play before but I will say that still scoring 10 goals in just 7 games and scoring quite some beautiful goals means that Messi has returned to good football.At this point I have no doubt that most likely Inter Miami is going to win the title there in the MLS while I think PSG is a long gone forgotten memory by Messi.Of course his family feels better too in USA as USA is North America and they come from South America so most likely the lifestyle difference is not that big especially in Miami which is populated by South Americans a lot.
Inter Miami won the title, and Messi won 2 personal titles as the top scorer and as the best player in this competition.
He was teased when he decided to go to Inter Miami because this club is weak, but he managed to answer his decision well, and it seems like he's just trying to keep playing not looking for popularity anymore but that's what he still gets in MLS without having to do controversy.
