If I remember correctly, the Latin American teams were very lucky in the World Championships on their continent and mostly unlucky outside of their time zone (Argentina won the World Cup for the first time in a "foreign" land). If this pattern continues, then Brazil will indeed have increased chances for the title, although in fact there, starting from the quarter-finals, the percentage of players playing in Europe will be close to 100.
Yes but although I have never been to South America, I feel like the fans can contribute a lot to their teams' successes. I know that this didn't work out very well in 2014 against Germany, but still the crowds are amazing there. But I still think that even in three years from now France is probably still the dominating force in world soccer. It is unbelievable how many young outstanding talents are spread all over European soccer. England and Spain also have quite a few, but France is all set for several years to go.
I haven’t been to Brazil either and unfortunately I won’t be able to get to that legendary Maracana, which could accommodate 200,000+ spectators. I would like to know what is the atmosphere at the game when so many people are watching it live

France looks dominant and, unlike Spain in the early 10s, the end of this dominance is not visible - they have enough players in every generation who can win everything. But due to the fact that the tournaments are short and the randomness is high, I think we will see not only France on the podium.
