Arsenal are reportedly interested in signing Sporting Lisbon teenager Joelson Fernandes.
The 17-year-old is yet to make his first-team bow for Sporting but has featured on 28 occasions for the club's Under-23 side this season, scoring five times and contributing two assists.
Fernandes has also represented Portugal at Under-15, Under-16 and Under-17 level, finding the back of the net on four occasions across the three different age groups.
The report, though, claims that Sporting are desperately attempting to tie the teenager to a new contract with a €100m (£90m) release clause to protect his value.
Fernandes's current deal at Estadio Jose Alvalade is due to expire in June 2022.
