London's biggest clubs are eyeing Athletic Bilbao youngster Gorka Guruzeta.
The Spanish forward is set to play against Manchester United Under-23s in the Premier League International Cup, with top clubs monitoring his contract situation.
Guruzeta, 21, is out of contract at the end of the season and can move without a fee.
Premier League sides will need to pay training compensation to bring him to England but it would be fraction of his market value.
Newcastle boss Rafa Benitez is also an admirer of the youngster, who can play as a winger or striker, and could join the race to sign him.
