If Argentina met Portugal in the final it would be incredible. How the two countries that have two star players meet at the biggest football party in the world. Moreover, this is likely to be the last World Cup for them (Messi and Ronaldo). If this really happens this will be the most favorite match during the Qatar World Cup in my opinion.
It will be a dream match. Cristiano Ronaldo vs Lionel Messi. I don't have much concerns about Argentina. They are one of the best teams right now. But the big question is about Portugal, as they are basically a one man army led by Ronaldo. If Ronaldo is properly marked by the opponent team, then Portugal will lose the match for sure. Hardly anyone else in their team has the capability to win matches. I am a big fan of Ronaldo, but I am being realistic here. In this tournament, I don't think that Portugal's chances are very bright.
It will be incredible to see Christiano Ronaldo or Lionel Messi lifting the FIFA world cup before they retire but as we all know it takes more than just individual effort to win the world cup. Though Portugal and Argentina have good squads to compete at all levels of the competition and would be nice having both of them play in the finals but some teams tend to be favourites to lift the trophy every year.
