I don't feel that in this case PSG doesn't respect Messi because regardless of any condition he is indeed one of the players who is made like a golden boy there too.
His performance is also still quite decent, it's just that there are still many people who expect too much about better conditions even though it is certain that with this age condition it is a bit difficult to do and the current top assists are actually proof that Messi's performance is very good there.
On the other hand, for Barcelona, they need to make some moves by releasing lots of players to bring in Messi.
It doesn't really matter, it's just that it's a shame if they want Messi, whose time will soon be over at the expense of several young players whose time is just about to grow.
PSG surely have a big respect to Messi. They were on the line right away to sign Messi after seeing him as free agent. Maybe he needed some time to adapt to a completely new team and strategies but PSG officials didn't see it as a problem at all. We have all witnessed how big effort Messi has made so far after starting to adapt to the style of his new team. His contribution level in this season has also been very big honestly.
The problem in this case, I think, is not the PSG, but the supporters who can be said to be less friendly to Messi, and that is evident when not a few fans blame Messi when PSG cannot play well, even though logically they blame one player. obviously makes no sense since it's a club game.
Even though they are angry because of the negative results, of course they have to think more rationally in this case.
On the other hand, a salary cut of 25 percent of current income is also a bit of a hindrance because Messi doesn't want that.
Xavi says that he would like to have a reunion with Messi if possible but I don't know if this transfer would really happen this summer. Above all else their financial situation will be really important before going for him. Because maybe they can have difficulties again to meet his demands after spending a lot of money on new transfers and salaries. I think it is better to invest into young and talented players for Barcelona.
With the reason he left because he didn't want to get a cut then moving to Barcelona is something ridiculous actually if he did decide to return because here even he will get a bigger cut under the conditions you said. Barcelona doesn't need to feel that they can be proud of themselves because they always get away from the abyss of financial problems because by forcing to bring in Messi, in my opinion this will clearly invite reactions from many parties.
