I'll use your post to add something:

Yesterday it was reported in the Brazilian newspapers that the Brazilian national team will hire the current Fluminense coach, Fernando Diniz, as interim coach of Brazil, with a 1-year contract until Ancelotti arrives.
The coach will have a curious position, where he will coach Fluminese's team and the Brazilian national team.

This wait for Ancelotti has been criticized by most Brazilians, fans and the media, as they find it absurd to wait so long to start a job.

Two doubts remain in the air:

1 - If the coach Fernando Diniz gets great results, can he not screw the future contract of Ancelotti? Since Real Madrid itself does not seem so happy to see the departure of its coach

2 - Could Ancelotti talk to the Brazil coach, even being in Real Madrid, to start a work "at distance", where he can ask them to start working the way he prefers?
