Brazil still has plenty of time to improve and make things better, so they can regain the trust of their fans around the world. As a team that has an even squad depth in every line, Brazil is still the favorite in every competition, especially in the World Cup, even though they are currently slumping in the qualifying standings, but personally I think they will gradually rise again.
New Brazil manager Dorival Junior have enough time for preparing team playing in Copa America six months later, I think under era Dorival Junior Brazil seems promising will have better achievement because he know with Brazil culture due previous teams before with Flamengo. Brazilian Football Confederation or CBF have right decision announce early for new manager after failure sign Carlo Ancelotti and Dorival Junior as new Brazil manager have longer time preparing teams.
Currently some people not know well with Dorival Junior but he was success won Copa Libertadores last season with Flamengo, I think his achievement is reason from Brazilian Football Confederation or CBF show him as new Brazil manager for playing in Copa America 2024 and prepare teams qualify to FIFA World Cup 2026.
All I can say about Dorival Junior and Brazil is this Brazilian coach was definitely one of the best options Brazil could have for their team.
Dorival Junior is a coach with lots of experience in different Brazilian teams and his last experience was in São Paulo where he won the Copa do Brasil with this team, but I don't think if he could be the best option for Brazil.
