Manchester United's Brazilian twins Fabio and Rafael have revealed that former Red Devils assistant boss Carlos Queiroz is keen for them to switch allegiance to Portugal.
The 18-year-olds, who have represented the South American nation at under-15 and under-17 level, are yet to make their debuts for the senior team.
"I still dream of the national team. I am young and still have a lot to prove," Rafael told GloboEsporte.com.
Fabio added: "Queiroz has already worked with us. He likes both me and Rafael and calls us any time. He really wants us to play for Portugal, but I don't know.
"Every (Brazilian) guy wants to play in the yellow shirt and play in a World Cup. I'd rather wait a little bit."
Fabio revealed Queiroz had initially hoped both players might represent Portugal at under-23 level before stepping up to the senior side.
Both Rafael and Fabio hold Portuguese passports as well as Brazilian ones.
