Tottenham are among the clubs following Vasco da Gama's young forward Rayan Vitor.
Club scouts have been monitoring his progress in recent months and checked on him again last week when he scored in a 2-0 win over Cruzeiro.
The 19-year-old was a prolific goalscorer throughout his youth and while his strike rate has dropped, he is still making an impact at first team level.
Quick and aggressive, Rayan is tipped for a national call-up to Carlo Ancelotti's senior Brazil squad also.
He has a release clause set at £34million but suitors are hoping he can be prised out for less.
