Messi's fitness is still very good. He will not decide to retire so soon. He will be associated with football for another 3-4 years. And the most important thing is that he will not decide to retire from the PSG club. There is a possibility that he will come back to Barcelona. And from Barcelona, he will announce his retirement. Or he will announce his retirement from a club in Argentina, where his career began. I think we will see Messi in Barcelona jersey again. Even if it is for a very short time.
I doubt if Messi would be able to play competitive football for another 2 years. Players' performance tends to decrease faster when they are getting old. No doubt he is strong and fit but he might retire in the next one or two years. Messi is now about 36 years old. He still manages to perform consistently well as a young player. As players age they cannot maintain fitness. But Messi's fitness is still excellent. And he's not dealing with as many injuries. I would say Messi will be able to serve his team well for several more years if he does not face any fitness issues. Messi still needs to be aware of his fitness. And the idea is that Messi will be able to easily maintain his good performance for at least 2 years. He can maintain his fitness till at least 38 years.
