I am fed up with Brazil's new coach's training and match tactics. I don't know how he builds his squad. Brazil played against Uruguay in the quarter-finals of the Copa America. This team was very strong. In this match, the Brazil coach put 17-year-old Endrick at the center of his attack. I don't know why he kept an inexperienced player like Endrick in the center of his attack.
Brazil coach should be more conscious in team formation and match strategy selection. If he can't do it then Brazil management should definitely look for a new coach.
If Brazil is ambitious to perform well in the next World Cup, they must change the coach. The performance shown in the current Brazil game is very easy to anticipate by the opponent. I think if Brazil has a better coach than Dorival Junior, with the squad that is in the current Brazil team, I am sure they will perform better in the next World Cup. Brazil has indeed shown the instability of their performance. They lost to Spain and drew against America, and even in the Copa America Brazil managed to be held to a draw by Costa Rica and Colombia.
if they want to improve I think it's not too late. but they really need to get an experienced coach.
