La Roja were beaten 3-0 by the Selecao in the final but could end up facing Luiz Felipe Scolari's men again as soon as the last 16 of the World Cup, though the Barcelona midfielder is hoping the reigning world champions can get their own back in the final.
"Here’s hoping we can get revenge! Why not in the final?" he said in an interview with Fifa.com. "Obviously anything could happen, considering it’s a World Cup and the difficult group we’ve been drawn in – and their group is no breeze either.
"But football always gives you the opportunity to get revenge. Here’s hoping it’s at the World Cup and at as late a stage as possible.
"That Confederations Cup final was a game in which everything went against us and they got all the breaks. But credit where credit’s due: Brazil played better on the day. Nevertheless, the whole experience will stand us in good stead for the World Cup.
"Now we’ve had a taste of the weather and we know what we’ll be up against if we face Brazil. In my opinion, they did well to overcome the pressure of being the host nation."
"We’re focused on the fact that we have been drawn in a really very tricky group, one of the toughest at the World Cup," he added.
"We are going there to compete and we’re desperate to give a good account of ourselves and retain the trophy, but we are keeping our feet on the ground.
"We know how hard it is to play at the World Cup to begin with, let alone with the group we’ve been handed. It’s got to be one of the two hardest groups, if not the toughest.
"A match that was the World Cup Final last time round is now a group-opener. That’s how draws work. It’s pot luck, so we’ve got the Dutch again and a very strong-looking Chile, whom we’ve faced several times recently.
"And then there’s Australia, who are a bit of an unknown quantity. On paper it’s a really tough group."
Spain are aiming to become the first nation to defend the World Cup since Brazil in 1962 having successfully bagged back-to-back European Championship trophies with their win in 2012.
