PSG won the league but I think I think the teams in not happy at all because they didn't reach the goal they wanted to reach.
PSG bought many superstar players and they spend too much money to keep players like Mbappr the reason for spending all this money was mostly because they wanted to achieve something in the Champions League otherwise for winning the French League they didn't need this much investment.
Winning the France League title is a regular occurrence for PSG but their main target is the Champions League trophy which they have so far failed to win. They kept players like Mbappe and signed big name players like Messi to their club only to win Champions League trophy but to no avail. The team was eliminated early in the Champions League after losing to Bayern Munich in the UEFA Champions League. Until now they believed that they can win the Champions League trophy but now they may not have that belief because Lionel Messi has left the club, Neymar may leave PSG and Mbappe is likely to be signed by Real Madrid. Sergio Ramos may join the Saudi League. If these key players of the team are gone, it will be difficult for them to win the league title.
