Andreas Pereira has confirmed that he only intends to play for the Brazilian national side despite being raised in Belgium.
The Manchester United under-21 player was raised in Belgium and has represented the country youth level, turning out for the Under-15, 16 and 17.
However, being born to Brazilian parents, Pereira has confirmed that his heart lies with the five time World Cup winners, not Belgium.
He told Esporte Interativo: "My heart is with Brazil.
"My dream is to play for the national team.
"I played for Belgium at youth level but it does not have that feeling that I imagine it will be playing for Brazil. It's different."
The 17-year-old moved to Old Trafford from PSV Eindhoven in 2011 and was touted as one of the finest players of his generation with a number of clubs interested in his services.
If true, it represents another blow for Belgium after another Manchester United starlet, Adnan Januzaj, turned down a call-up to the national team before the latest run of World Cup qualifiers.
The 18-year-old stunned the Premier League with an impressive brace for United against Sunderland after being gifted his first Premier League start by David Moyes and has been targeted by a number of nations - including England.
Januzaj still hasn't announced who his international future lies with and Pereira admits his Manchester United team mate has given no clues away in training.
He continued: "He said nothing to us, but is always very calm when training with us. He never talked to other players about which national team he will defend. It is something very particular."
