True, while Messi himself joined PSG in the 2021 season and ended it in 2023 which means that during these two season Messi did not contribute anything to PSG in the UCL competition, Messi did play well for PSG but that was only in Ligue 1 in his last season, namely 2022/23.
Only Neymar and Mbappe are the best players for PSG, Messi is just player with an expensive price and high salary but is not dominant player for PSG success, now they are all just memories for PSG so that in the future maybe PSG will give birth to young potential that can make them stronger again.
But to say that Messi did not contribute anything in my opinion is also too much, because he can also contribute, it's just that maybe he did not contribute as expected, that's all. He had a hard time after leaving Barcelona, and indeed it was the first time he had a new team after years of being in the Barcelona squad. And if we look at it, his departure was not entirely his wish, but Barcelona was in a bad situation so they were forced to sell Messi. So maybe one of the reasons why it took him so long to adapt to Paris Saint Germain's game, because his heart was still left in his previous team.
Just as fairly reliable goal scorer in the Domestic League, that all I think Messi contribution while being part of PSG, don't talk about other competitions in Europe like the UCL because Messi performance with PSG in the UCL is quite bad and has nothing to do with feelings that are too deep because he left Barcelona because professional player after leaving then he will focus and try to play as well as possible for the team he is now defending.
By the way yesterday PSG managed to win the match against St-Etienne which is lower team that is currently in the relegation zone, this 2 - 1 victory made Dembele the center of attention because he created 2 goal for PSG victory and so far Dembele has been the most prominent player in every match played by PSG, he is like substitute for Mbappe.
