I think Messi will also give other players the opportunity to progress. Having Messi with the Argentinian national team at the upcoming 2026 World Cup will certainly increase the morale of other young players. Messi is old and he knows he won't be able to play like he used to. This means that Messi is likely to be played in important matches and be a substitute at crucial times. Messi can increase the morale and self-confidence of young Argentine players and I think Messi will still have an important role for the Argentine national team in the World Cup.
It's always a bit challenging to be in the team with a superstar, because the coach will usually get pressured to put him in instead of trying the new players.
It also won't make any sense to have Messi at the bench the whole time, so I guess it would really be the most sensible thing to do to simply give them the opportunity to play by retiring while he is at the top.
I mean, what if he plays the next world cup and doesn't win it?, he will definitely retire after that one, and it would be a bit more disappointing than retiring as a champion.
Having a player like Messi can definitely put Argentina and their coach under more pressure and that's clear for me. Even a few days ago when they had a problem between Messi and Scaloni, I saw some news about Scaloni leaving the team and while he was leaving none was supporting this coach while he was the coach of the team and but people were usually supporting Messi and they even wanted their coach to leave because of one player, however, that one player is even getting old and he is far from his good form.
I actually don't think he is going to play in the next World Cup because the next World Cup is a long time away. Actually, I do not see him performing well and being ready for that World Cup that he was for the last one. I am pretty sure that there will be younger players who will show those performances for Argentina by the time.
Yes, I also agree that it will be better for him to retire as the champion instead of someone who was unable to win the last World Cup that he played. You know, I was kind of hoping for watching a Portugal versus Argentina or Ronaldo versus Messi match up in the next World Cup. But it does not matter how big of a fan I am of them, I have to accept the fact that it is over.
