Messi can't possibly still enjoy himself with this team in the league? Supporters also seem to be turning against him more and more, I think. For a great player like Messi, just becoming champion in the league is not enough to win that as a prize in 1 season. PSG has a strong team with great players, but as a team it is not possible to achieve international successes.
Messi is just like Ronaldo that club should not expect much from him. I'm not surprised about Messi not bringing good result for psg. I think Messi has already gotten what he want as a great footballer but this time he can't do more than his strength to give PSG the best. The problem of psg is beyond players.
