Brazil has not won the World Cup for a long time. I saw Brazil win the World Cup in 2002. But that was also almost 23 years ago. A long time has passed but Brazil has not won the World Cup.
In the last season, the fans had high expectations for the Brazil squad. There were many talented and star players in the squad. The Brazilian squad was probably the most expensive squad in the World Cup. Although they played well in the first round, Brazil's performance in the second round was very weak. As a result, Brazil failed to win the title. Brazil lost to Croatia in the quarter-finals.
So far, we have seen Brazil's fans blaming their coach. But now Brazil has an experienced coach like Ancelotti. If Brazil cannot do well in the next World Cup, then who will the Brazilian fans blame?

That game against Croatia in the last World Cup was a bizarre defensive failure, even Neymar was furious that day. Well, today’s Brazilian national team is just a shadow of the strong squad it once was, and if they don’t get a good result in this World Cup (which I believe will be the case), the real blame will definitely lie with the CBF. However, the fans and the sports media will surely put the blame unfairly on Carlo Ancelotti. It’s a loop that keeps happening in Brazil, whenever there's a bad result, it’s never the team or the executives, it always falls on the coach. A clear example of this is how Brazilian clubs operate, with a huge rotation of head coaches.
In the last few years we have seen Brazil management and fans blamed their coaches for the bad performance of Brazil. And it was quite reasonable. Brazil's coach's match strategy was strange. Even his squad was strange. He kept the players on the bench who was in good form. He used his favorite players to the starting XI. For these reasons Brazil's performance was weak and irregular, even after having a strong squad.
However, Ancelotti is a very experienced coach. He has proved his ability. Ancelotti is successful in managing in the club football. However, this is the first time Ancelotti has taken charge of a national team. The situation in Brazil is now shaky. So so far it is not said that Ancelotti will be successful. However, the Brazil Board should rely on Ancelotti and let him work independently.
