I assume you are referring to Brazil's very poor performance at the 2014 World Cup in Brazil and the disastrous loss to Germany in the semi-finals or the fact that Brazil has not been a world champion for 20 years?
Personally, I see Brazil, along with France, as the main favorite for the title at the world championship in Qatar.
However, at this world championship, there are still plenty of high-quality and strong national teams such as England, Germany, Belgium, Argentina etc. and a very uncertain competition awaits us.
The team that is most ready to withstand a very difficult and strenuous competition will win.
Brazil's crushing defeat of Germany in the 2014 World Cup certainly shocked football lovers. By the way, the World Cup which will be held in Qatar in terms of quality, Brazil, Argentina, Germany, France, will be the group winners on paper. although in the match later all teams have the potential to beat the big teams. Brazil is a superior team with many quality players, but I have another perspective, I believe Brazil will be knocked out in the semi-finals, I prefer Argentina to meet France in the final. This is just a prediction, it doesn't determine what will happen, we can enjoy every match that will be held later while betting.
