Brazilian passion for the soccer is without any doubt and their history is also having good success but sadly now their presence is at their lowest level even still they are having many big players those are giving their best in different leagues and also can give their best for their country, but sadly things are going not as expected because they are lack of leadership which is always important for win their performance is having good depth but their aggression and offense is not working as they were doing in the past.
Brazil needs to work on their system because if they are able to have foreign coaches into their league and also for the national team then surely this could be good change, and we will be having better results and many other developments which will help their players for having improved performance and results now they are having challenges in coming days as they are looking for wins into World Cup qualifiers because due to poor performance they are facing tougher time.
The problem is that Brazilians love football, but they do not consider it as a job after they make the money. There has been a lot of Brazilians who did not take care of their body, of course there are ones like Vini who do, but there are a lot who never put any emphasis on keeping their body healthy. They play because they think it's fun to play, not because they see that as job.
Look at Ronaldinho, one of the most entertaining football players in football history, I have never seen him in a good body shape, dude was just normal until he retired, that's it. Look, I am not expecting Cristiano Ronaldo style situation, but Neymar basically never went to lifting room all his life evidently, and his body can't handle all these injuries and life style, so he is basically done. He had fun, made some money, got rich, now time to retire.
