It is true that when Messi was at Barcelona, he had better quality in his game, compared to what he has done at PSG. On the other hand, he in the Argentina national team has been doing much better than he was before. It's clear that he has been much more focused on playing for his country, and determined to do his best. So I believe that in this Worlds he will try to be in the best possible shape.
In Barcelona he played for quite a long time, this squad has raised his name to the peak of his career, the combination and mix of football at Barcelona belongs to a category that is quite perfect for a Messi, so many titles have been won there together with the team, but speaking for the country, Messi there are still very few achievements given, so this year's world cup is the last chance to prove it
There is definitely a difference when it comes to playing for club and country. Not that they are unprofessional but if they are at the end of their careers surely they are more willing to do more for their country. Moreover, this is likely to be the last World Cup for several star players, one of which is Messi.
Apart from all that, we will watch the game of the players who are now old. It's very sad.
At the club they train and play so often, so that the combination of one player with another is more pronounced, compared to playing for the country, the professionalism of a player is not an excuse that a little time for the country is an excuse, but I think it will affect the final result of every game played in the country
He was even determined when it came to his country.
But the problem in this case will be a bit difficult because he still seems to be playing alone later considering sometimes with things like being focused like this apart from being unsure of his partner it also becomes quite bad because he seems to be fighting alone.
Their country never loses good players and has big names there but things like this will not be suitable if all eyes are only on Messi.
Argentina have great players who are able to play collectively together with Messi, but because the mix in the squad is not achieved, so Messi seems to be fighting for himself for his country, this is due to the time together, not enough training and coupled with the coach's strategy which may not suit his style. every player
Also you should look into the fact that at Barca, he was in his prime and was the main man while in PSG, there are other superstars that have plays designed for them as well. Naymar and M'bappe can create their own goals or facilitate others with their brilliance and the team just doesnt rely as much as Barca would with Messi. He doesn't have to play his peak in a league that PSG were dominating anyways, with or without him. That being said, for Argentina, he is definitely required to perform or the team collapses in attack. Even though they have good attacking talent in Argentina but you need a player like Messi to unlock opponents defense.
The quality of players is also influenced by the collective collective of players, where the games they play relate to each other, no doubt their heyday at Barcelona is also the main player at PSG at this time, but collectively it is not only the individual players who move to PSG , Barcelona's peak moment of glory also had the right time, so there were many reasons that influenced the club to experience its heyday
