Messi's PSG contract was originally reported as a three-year contract, but in actuality it's a two-year deal with an option for a third year. So while Messi can trigger a third year of his contract at PSG, it seems more likely that he'll sign a new deal for 2023 and beyond, either at PSG or somewhere else.
This seems by far the most likely option, as Messi has an ideal situation in the French capital. According to Barcelona vice-president Eduard Romeu in mid-January, a reunion with Messi would be "financially possible" for the club should he depart PSG as a free agent, whether it be this coming summer or the summer of 2024.
