The Selecao were expected to go on and win the tournament but instead finished fourth as a 3-0 defeat to Netherlands in the third-place play-off followed their humiliating semi-final loss to Joachim Low's men.
Ramires admits that their trouncing in the last four will be "a stain on this group" for the rest of their lives.

"We can't point at each other right now. We all lose together. This result will be a stain on this group for the remainder of our lives but we have to try and keep walking tall, to look for comfort with our families.
"We are sorry to the Brazilian people who supported us all along. They showed that even [on Saturday]. We dug out something good to get the fans believing again.
"We saw the people in the streets while we were in our bus, some of them left home to at least wave at us. We are disappointed for ending it like this."
The hosts put in another poor performance in the loss to Netherlands and Ramires confessed that his side were completely lost on the field against the Dutch.
"It's hard to analyse. I can say we are somewhat lost in the pitch at the end," the Chelsea man added. "We had another opportunity, not to overcome the last defeat but at least to end the World Cup in a positive fashion."
