While I am one of Messi's biggest fans in South American team, I believe the current team will need luck to win the world cup. The last time a South American team won the FIFA World Cup was Brazil. As a result, Argentina's chances are stacked against them. It doesn't matter what, European countries always dominate. Yes, it would be incredible to see Messi or Ronaldo lift the FIFA World Cup trophy in 2022.
I doubt Portugal will reach the final, although I would like to see it. Portugal has the players to get there, it remains to be seen if they will be focused enough for that.
But it would be very nice to see an Argentina vs Portugal final, because they are two teams that have never played against each other.
I think based on the group where Argentina is it has all the chances to go really far in this tournament,why not reaching the final and winning it.If they happen to play against Brazil I don't know how that game would end,most probably with penalties but whenever these two teams have played against each other in the Conmebol qualifiers Argentina has won when playing at home and Brazil has won when playing at home,in a neutral field I don't know but hopefully Argentina will not face at all Brazil except maybe at the final.The players of Argentina are some of the best in the world in whatever league they play and I think it is finally time for them to win a big trophy.
