Liverpool are reportedly interested in signing Porto's highly-rated midfielder Vitinha this summer.

The 22-year-old has been a key player for Sergio Conceicao's side this season, scoring three goals and registering four assists in 40 appearances across all competitions.

According to Portuguese news outlet O Jogo, via Sports Witness, Liverpool are among a number of European clubs, including Bayern Munich and Lazio, who have been following the midfielder 'with a lot of attention'.

Vitinha endured a difficult loan spell with Wolverhampton Wanderers last season, starting only five times in 22 appearances in all tournaments, but he has since developed into a first-team regular with Porto this term.

The midfielder is under contract at the Estadio do Dragao until June 2024 and is believed to have a €40m (£34m) release clause.

Spanish giants Real Madrid have also been credited with an interest in Vitinha, who made his senior debut for the Portugal national team last month.
