In addition, Paraguay managed to get a ball into Brazil's net with only 30% of the ball in their possession, which means that Brazil's finishing is weak and Brazil's defense is also weak.
Argentina have lost but the important fact here is that Argentina have probably lost only three matches with this match in the last five years.
Brazil lost to Paraguay and the Portuguese news channels that I have been following are not talking much about this defeat because although they recognize that the Brazilian national team is not performing well, they have always managed to do better when they play against Paraguay. To give you an idea of what I am talking about, Paraguay had not been able to beat Brazil since 2009, it had been more than 15 years without them being able to beat Brazil. So this defeat by Brazil goes down in history.

What is very worrying about this qualification for Brazil is the following:
Games = 8
Wins = 3
Defeats = 4
a team that has the history of the greatest achievements in the World Cup, a team that was fearsome on a global level, looking at them now you realize that they are in decline. But even so, I have not seen at any time that they talk about firing the national coach and looking for another who is international. It seems that the Brazilian Football Federation does not see this poor performance as being a big problem. It's very strange how the highest football body in Brazil reacts to this situation. Normally any organization would be panicking and talking about dismissal, because we are talking about 8 games and 4 defeats, precisely in World Cup qualifying games. These are not friendly games, they are serious games. But there is no talk of dismissals.
