Actually, Brazil has never been coached by foreign nationals outside Brazil.
Brazil has been trained by foreigners but in the old days
1 Ramon Platero (Uruguay)
Brazil's first foreign coach was Ramon Platero. This Uruguayan passport coach handled the Brazilian national team in 1925.
2. Joreca (Portugal)
The next Brazilian foreign coach is Joreca. Interestingly before coaching the Brazilian national team in 1944
3. Filpo Núñez (Argentina)
He coached the Brazilian national team in 1965.
That's why when we saw the news about Ancelotti joining Brazil, even the president of this country said they didn't want to have this coach and they preferred to use Brazilian coaches for their teams.
Brazil is a country that won the World Cup title more than any other country and that's why it's pretty much normal to see they prefer to don't use the non-Brazilian coaches.
But currently, they are not in a good situation and maybe Ancelotti join the team soon.
It seems to me that in Brazil, leaders like to wear wooden glasses. Honestly, there are so many jokes coming from them that sometimes I tend to laugh so much that I can't contain myself. For example, regarding the Brazilian national team, the players that make up the Brazilian national team's squad are players coming from teams abroad, mainly from the big European teams, and when they hire a Brazilian coach who only has experience with Brazilian teams ( Brazilian local league), it is unlikely that this same coach will be able to create good strategies and make the team play very well in a way that brings good results, mainly because in Latin America there are already many national teams with good players and coaches
What makes Brazil no longer a team with extreme dominance over other teams, just look at the list of players from Argentina and Uruguay and we will see that they are two teams that have good players who play in Europe and have good coaches, and that This alone makes them capable of beating Brazil many times in a row, while Brazil has had players who are constantly involved in controversy, it is difficult for good Brazilian players to reach 38 years of age playing for major European teams. I sincerely doubt that the Real Madrid coach will accept the role of Brazil coach, that would only destroy his good reputation
