There is a possibility that Portugal and Argentina could play in the finals, just like almost most world cups. Which is why I am still holding out hope one last time, I know that 4 years from now it would be quite difficult for Ronaldo to be the striker for Portugal, and maybe Messi won't be there as well. This means this is the last time that we are going to see Argentina and Portugal having a chance of finals against each other to see these two giants.
I know that Argentina does have a chance but Portugal doesn't and they are given low odds but I just hope some pure luck and something happens and we watch that. I guarantee you, in ANY combination of finals, that would be the most viewed finals ever.
It has been a common thing that either Argentina or Portugal to meet along the way or one of them making it to semi finals or even the final, but this time i think they both have something new to offer as a surprise in their 2022 FIFA world cup, though having the role of the key players in the two countries isn't the major thing that gives them hedge to making it, but the coordination in each team together along with its team players goes along way, i wish Messi and Ronaldo could perform more better than they have been giving in their respective clubs for their country.
