The 27-year-old enjoyed an impressive 2019-20 campaign for his Portuguese club, scoring 13 times and providing 12 assists in 49 appearances in all competitions.
The defender could allegedly be available for as little as €25m (£22.8m) during this summer's transfer window as his contract at the Estadio do Dragao is due to expire next June.

Manchester City have also previously been linked with Telles, who made his Brazil debut last March. body check tags ::
