For me I'll be supporting the Brazilian national team to win this summer's edition of the Copa America but that doesn't mean that I'll be surprised if Argentina overpowers them to claim the trophy. Football is one sports that's been connecting people across the globe irrespective of their race or beliefs so despite the fact that I'm not from the continent, I'm looking forward to the start of fge competition
If you choose Brazil, of course, I personally prefer to see that Argentina is a strong candidate to win the copa American trophy again this year, because I think with the current squad, of course, Argentina looks more perfect and very balanced both in terms of their performance and experience, if you look at the Argentine lineup that does combine young and senior players, I think you would also think that Argentina has a greater chance than Brazil at the moment.
On the aspect of Argentina being the favourite to it this time around I think you are right. Their squad is still as solid as it was during the last world cup. They have even new crops of young players coming through their rank. Although Brazil are in desperate need of a trophy but I don't think they are going to end their trophy drought anytime soon.
