While Brazil had more possession, they gave the ball away cheaply on numerous occasions and struggled to contain the Serbia counter-attack.
I think Brazil is in trouble.
Suffice it to say, the power has shifted largely to Europe. Brazil use to look like the team to beat always, now not so much. But their team is always nonetheless very good. It still takes a Herculean effort to knock them out of a World Cup. For the record, since 1986, France defeated them 3 times, Netherlands were able to survive them in 2010.
