I think Messi is trying to be realistic now and he didn't want to make a blunder that would put him in the same situation a second time. We all know that he left Barcelona because Barcelona's financial situation was in turmoil and Barcelona has no option other than having to sell Messi. So if Messi has worries about returning to Barcelona, I think it is a reasonable thought because even though 2 years have passed, Barcelona still has problems with their finances and Messi knows the problem perfectly.
from this problem, Messi seems to be thinking about going to the Saudi Arabian team, which has a higher offer and there are no problems whatsoever with the team or players. there is a lot of news that Messi will return to Barcelona but realistically Messi has a great career and must match his salary. I don't blame Messi for wanting a big salary because it is equivalent to the performance he has at the moment.
on the one hand, it seems that there will still be a lot of news about which team Messi will go to, but I am more positive if Messi stays in Saudi Arabia.
