Portugal star Cristiano Ronaldo hopes Brazil fans will get behind their linguistic "brothers" and back his side -- at least until such time as their paths cross.
The World Player of the Year cannot meet this year's hosts before the semi-finals so the Real Madrid striker said he hoped locals would get behind his team as well as their own to help them on their way.
"I am hoping for great support from the Brazilians, it is a brother nation, speaking the same language," Ronaldo told SporTV, adding he hoped the two countries might face off in the final.
The pair met in the group stages in South Africa four years ago and played out a 0-0 draw in Durban as both teams advanced to the knockout phase.
Portugal, having come through the playoffs against Sweden thanks to Ronaldo's scoring heroics, first have to ensure they get out of a group including Germany, Ghana and the United States.
"We are not favorites -- but we shall try to enjoy it. We know we have a complicated group," Ronaldo said.
Portugal kick off their campaign against the Germans on June 16 in the northern city of Salvador, four days after Brazil open the event against Croatia in Sao Paulo.
