Fulham have made an enquiry for Deportivo La Coruna striker Pedro Martelo.
The 19-year-old forward also has interest from clubs in his native Portugal with his buyout clause set at a reported £903,000.
Martelo plays for Deportivo’s B team and starred for Portugal U19s last summer as they won the European Championships.
He is understood to be out of contract in the summer.
Cottagers’ boss Claudio Ranieri has already lined up several transfer targets to revitalise his struggling club in January.
Having been promoted from the Championship as play-off winners last season, Fulham’s struggles saw Slavisa Jokanovic sacked after 12 games.
He was replaced by Ranieri, but after winning his first game the Italian has yet to taste victory again.
The Premier League strugglers lost 4-1 to Manchester United on Saturday and now sit bottom of the table on nine points.
