Premier League sides Stoke City and Crystal Palace are among clubs showing interest in FC Porto midfielder Sergio Oliveira, A Bola can reveal.
The attacking midfielder has been unable to secure regular playing time at Estadio do Dragao after coming through the youth ranks and he is now looking to leave the Dragons at the earliest opportunity.
A Bola claims that the 24-year-old has suitors in England and Italy, with Stoke City, Crystal Palace, Cagliari and Palermo all keen.
The four clubs are closely monitoring the situation and they are expected to make their interest concrete ahead of the January transfer window.
Sergio Oliveira has enjoyed several successful loan stints, namely at Penafiel and Pacos Ferreira, and he went on to start 8 league matches for FC Porto last term.
However, having made just one substitute appearance in Primeira Liga this season, he is determined to leave in search of regular playing time.
