Yes, but PSG could upset Mbappe if they sign Messi. At this point in time, they would be far better off to just make Mbappe their star in terms of everything (salary, media exposure, position in the team etc.) in order to extend him. Signing Messi would be a hit on Mbappe's position in the club imo.
City don't have any stars with a big ego. So nobody would really be put off by Messi joining and instantly becoming the main star.
Lol.
Mbapp? would be upset because PSG sign Messi ? I don't think so.
What Mbapp? wants is win titles to stroke his ego. CL is the only one left with PSG. And signing Messi could give him the impression he could get closer to achieve it.
Also, PSG doesn't need to do anything to make Mbapp? "their star in terms of everything". He isn't thinking about renewing. Would be very stupid from PSG not to sign a player to appease another one who could leave in one year time.
At the moment, Neymar is the star of PSG and everyone knows it. If Mbapp? wants to have any say in a Messi purchase, he should start scoring some goals in CL knock out for us. He has only scored 1 goal in 3 years. Against MU.
PSG owners would be very happy to sign Messi just for the fame and to get one over Manchester City owners. That being said, PSG is already bleeding with Mbapp? and Neymar wages. Manchester is his best and only realistic choice. They offer PL + Pep + golden retirement in NY.
