Love is not enough for a country to host the world cup we know Brazil is the country where most people love football and there are many players in that country, but if they want to host the World Cup, first they have to have enough financial potential for the tournament and they need to have enough sports facilities and hostels but I don't think if Brazel and Argentina got any of these.
Lionel Messi's biggest gain is securing Argentina's World Cup. He is a living legend with nothing left to achieve in his football career except the World Cup. Finally this dream of Lionel Messi has come true now there is no more achievement left in his career he will be a living legend forever in our hearts.
I believe that he was already a legend even before any of that and people who think that he became even bigger legend after winning it are right but that doesn't mean he would not have been a bad thing if he lost neither. I think he would have been still a living legend even if he lost as well and that should have been the case.
I think it is obvious that people are overplaying the importance of world cup for his career, look I agree that it is a huge deal, but this dude won the most ballon d'ors ever in history, that alone would have made him legend as well. In the end, we are going to see him do as well as hoped for even after this age, but I think he could just look for money and not really care about any other reward and can be still considered a living legend.
