Porto's teenage midfielder Ussumane Djalo is attracting serious Premier League interest.
The 19-year-old has been hugely impressive in the UEFA Youth League this season.
Per The Mail, he has been watched by scouts from several clubs, including Manchester United, Brighton, Everton, and Southampton.
The Portuguese club have put a release clause in his contract, but it is only for £8 million.
The source adds that if a club does bid in January, they may be able to secure Djalo for even less.
Porto are not eager to sell, but they would accept a tidy profit on a youth player.
