Porto have convinced highly rated forward Andre Silva to sign a new five-year deal keeping him at the club until 2021, according to ESPN.
Silva, 20, only broke into the Porto first-team in December but has attracted a lot of admirers for his talent and series of impressive performances.
However, any club looking to sign the Portugal under-21 international will now need to match his €60m release clause (£51.8m).
Silva has scored in each of his last four matches for Porto in all competitions, including in both of their league outings this season – only Frederico Venancio has scored as many in Liga NOS this season.
