Here are the groups for the World Cup:
The Final will have one team from the top row and one from the bottom row.
This means that the final for the World Cup 2022 can actually be Brazil vs Argentina, both teams have been defeated zero times so far.
That would be an incredible final.
Good guess, but I think France or England have a better chance of facing Brazil in the final. But Brazil also need to beat Belgium, Germany or Spain. I think there are a lot of favourites for the final match, but certainly Brazil is the main one. Also, we must not forget that surprises often happen in big championships.
