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.
