It's ironic, but the reality is, and I'll explain. The fact that Brazil is five times world champion in Brazil has created a culture where a campaign is only considered successful when culminates with the title, which should not proceed! A good campaign does not always end title. But where I'm going with this? Well, in 2010, Dunga was the national coach. In "Dunga period", qualified for the World Cup in South Africa with only two losses and first in CONMEBOL, a flawless campaign. We won the Copa América 2007 in Venezuela and the FIFA Confederations Cup 2009 in South Africa, and were eliminated in the World Cup, just in the quarterfinals by the Netherlands for a goal difference (2-1). There is no doubt that Dunga had four years of success, but all it took was a game for which he received a barrage of criticism, as if there existed the years built a successful work. On the other hand, Germany has not won the World Cup, but continued to coach L?w, and see the result: won the World Cup!
On the day that the CBF (Brazilian Football Confederation) changing this terrible mentality keep changing technicians every time Brazil is eliminated from the World Cup, then we can win the sixth title. Dunga was sacked and replaced by Menezes, who finished sinking selection. Scolari straightened selection, but brought an inexperienced team full of beginners. Kaka and Robinho, who played in 2010, were not summoned by Scolari. What was missing the 2014 squad, was experience! And the truth is that it is impossible to win a World Cup with a team where 90% of players vying for their first World Cup. We feel it in the most terrible way with Germany, which brought a much more experienced team.
If the CBF had kept Dunga as coach, even after the elimination in the World Cup 2010 as Germany did with L?w, he would continue working and improving the squad that played in the 2010 World Cup. The problem of change coach is that the work don't continues, starts from zero, which is bad, in large part. And changes both Brazil coach because, here, the campaign is only considered satisfactory when culminates title. The Brazilian, having five titles, is extremely picky about this! Our five star, who are our greatest pride, are also a major cause of our destruction!
