The suspicion was that Messi had been saving himself for Qatar, that he really didn't care about PSG at all and had only joined the perennial Ligue 1 champions as they were the only club willing to meet his exorbitant salary demands.
Just like his good friend Neymar, he was held up as a symbol of everything that was wrong with PSG and their 'bling-bling' recruitment policy.
As one PSG supporter told GOAL back in 2023, "Messi was more of a marketing deal than a sporting signing. He ended up representing everything we hate about the QSI (Qatar Sports Investment) project for the past three or four years".
One can certainly understand the sentiment, as Messi and PSG always had the look of a marriage of convenience, one motivated more by financial gain than sporting success - and thus doomed to fail right from the start.
They did have one thing in common, of course. Both desperately wanted to win the Champions League: Messi had lifted the trophy four times but not since 2015, while PSG were still waiting for their first title.
However, Messi wasn't the solution to the Parisians' problems. On the contrary, he actually exacerbated them, because another superstar was the last thing PSG needed from a sporting perspective.
They already had two forwards unwilling to do any defensive work; they simply couldn't afford to carry another - no matter how gifted. The likes of Vitinha were, thus, left with far too many "chores" to do, resulting in another dreadfully imbalanced PSG team falling at the last-16 stage in each of Messi's two seasons at the club.
