Flamengo are fighting to keep hold of star striker Adryan from Manchester United.
Tuttosport says Flamengo president Patricia Amorim has declared they must secure Adryan to an extended deal to keep United from 'stealing' their teenage star from them.
United chiefs have invited Adryan, 16, to England for trials after spotting the youngster at the U17 South American Championships.
Adryan, who is also interesting Juventus, has a deal with Flamengo until 2014.
Brazilian football judges have likened the youngster's silky skills to legend Zico.
