Goncalo Cardoso could leave Boavista for the Premier League or Serie A with Watford, Inter Milan and Lazio all linked.

Watford are battling Italian giants Inter Milan to sign the highly-rated Boavista defender Goncalo Cardoso, according to the Mail.

The Portuguese U19 international has burst on to the scene in his homeland this season, establishing himself as a key player for a Boavista side stuck in the middle of the Primeira Liga table.

It is understood that Watford have been keeping close tabs on his developments over in Portugal. The Hornets are reportedly ready to strike a deal to bring Cardoso to Vicarage Road before he registers on the radar of some of Europe’s biggest clubs.

Inter Milan are already interested, as are Serie A rivals Lazio. As it stands, it is not sure how much Watford would have to pay to sign the teenager, who plays as a left-sided centre-half.

Cardoso is not the first exciting youngster to be linked with a move to Hertfordshire this week. TEAMtalk claimed recently that Watford are interested in the Brazilian striker Lincoln, another 18-year-old who plays for Flamengo.

It is understood that Lincoln would cost a club record £30 million if Watford want to sign him.
