Brazil is a country in which people like watching and playing football more than many other countries while Brazil doesn't have a good management system to manage the team and have better performance from the younger players they have got in this team and that's why Brazil is not currently in the good situation like other counties and they don't have good situation ay all however after using the new coach they can have better performance time after time.
Just like in other countries when a child is born they dream of becoming a doctor or an engineer, if a child is born in Brazil he dreams of becoming a world class footballer from childhood. Family helps children to become world class footballers and he was obsessed with football from an early age. It is natural that world-class footballers will be produced in such a country. Brazil has world class footballers and Brazil football team is the most expensive football team in the world but despite having such an expensive football team they are always unsuccessful. The major reason behind this is the lack of a good quality manager. If an experienced manager had taken charge of this team, the mission of this team would have been fulfilled long ago.
Brazil may have realized this but of late, Brazil have been looking for a manager at a time when they can't find an experienced manager to lead this team which is why they are slowly falling behind the competition.
I think Brazil's team management and coaches only worry about Neymar is that he can get injured at any time.
