I don't think any coach can do this while we all know how much Brazilian Federation is also involved in this dirty game I read most of the players are now invited by the sponsors which are having huge impact into this Federation, and they are controlling all things around this in Brazil which is having serious impact on their performance and things are not favorable for Carlos Ancelotti to join this team as coach and bring his reputation into bad way.
They are having too much money involved in this game and most of the Federation members are having personal links which works for the players those are called for the national teams through sponsors and investors if we have something about this surely changes will be happened.
If it's true as you say then this is a really serious problem. I know Brazil is one of the most corrupt countries in the world. Even the 2014 World Cup which was held in their country drew a lot of protests from the Brazilian people because the government was seen as preferring the World Cup to seeing many of its people suffer. But I never thought that the Brazilian football federation was also involved in corruption. Brazil produces many world class players, they are even the best in the world cup to date with five titles. I think it's because CBF really develops talented talent in their country. If they are also involved in a corruption scandal then I think Brazil will sink and they will no longer be one of the strongest football countries in the world.
Tell me about some governments that provenly have not been involved in corruption when it comes to hosting events like World Cups. I am not freeing Brazil from blame here, but by now I doubt that any processes involving the FIFA are without corruption. Look at the World Cup 2006 in Germany and how many allegations there were in hindsight about corruption. In contrast to Brazil, there were no protests from poor people though.
I have just
found this article and it seems that Brazil miscalculated some of the positive effects the World Cup might have on the economy. Additionally, World Cups are coming with long planning phases and in that year Brazil underwent very low economic growth, but the consequence couldn't be to cancel everything.
Corruption is one issue that I believe can hardly be solved. See how Infantino works and speaks and it was no different with Sepp Blatter. The system seems to be corrupt inside out. Economic distress in countries where these events take place is another issue and I think the biggest problem is not so much the event itself, but the preparations, building infrastructure under inhuman conditions and dumping wages. It's also about sustainability when stadiums that were newly built for the World Cup get torn down shortly after.
Next World Cup coming with a lot of negative buzz is probably the one in Saudi Arabia.
