I am going to give my opinion as an Argentine and a lover, above all, of Neymar.
I think Brazil lost because Brazil always plays like Brazil.
A fierce attack and a weak defense.
They came out champions 5 times playing in the same way.
I also think that coach Tite was very responsible.
It is not possible to remove the starting forward in regular time and put on the substitute forward.
Players of the quality of Vinicius, Richardhison and Raphina must play the entire game, including extra time. They are players who can appear at any time with their magic and unbalance.
Poor Casemiro ran to everyone only in midfield, Lucas Paqueta is not a brand player and I think that having like 4 players up front should have balanced that midfield more. I think the best moment for Brazil in the World Cup was when Bruno Guimaraes entered for Paqueta and the coach never put him on again.
It is very strange that coach Tite has not drawn conclusions from the win against South Korea. The Koreans had 4 heads up that if it weren't for the great goalkeeper Adhilson it would have been another result.
There is no doubt that the game against the great Croatian team was a great game for Brazil, what's more, the Croatian goalkeeper was the figure of the game, taking out 8 clear goal balls.
For me, when they scored the goal from 1 to 0, they fell asleep, and they continued playing in the same way. This happens to me because there was never a defensive order, they did not know how to endure a result.
And I think that the coach did not put a virtue of Brazil, two point markers like Dany Alves or Roberto Carlos. They always played with those big forward markers and this time they didn't. What's more, most of the goals they scored against Brazil were through crosses from the side of the leading markers, which in this case were central markers that became leading markers, they didn't feel the position.
And well, lastly, I love the Brazilian lifestyle, in fact, I have expressed it many times on this site. But I think the celebrations against South Korea seemed excessive, and I'm talking about the celebration of the players. I think that goals are celebrated as a goal as always throughout life and I have seen great Brazilian teams such as the one in 2002 with Ronaldo, Ronaldhino, Rivaldo, Kaka, Roberto Carlos and Cafu who never celebrated such excessive goals. It seemed to me that in this case that the festivities were almost like a mockery but in the end it is my personal opinion.
Finally my great sadness for Neymar. I hope and hopefully he plays in the next World Cup and he can have the opportunity to win it, he is a Lord with all the letters and he deserves it.
