Paris Saint-Germain have reportedly made an opening bid of £19m for Porto's Alex Telles.
The versatile Brazilian, who is capable of playing on the left-hand side of defence or midfield, is out of contract with Porto at the end of the 2021-22 season.
As a result, the Portuguese outfit are allegedly keen to cash in on the 27-year-old rather than see Telles walk away for free when his deal runs out next summer, and PSG are said to be the favourites for the defender's signature.
According to A Bola, the French champions have tabled an initial offer of £19m for the Brazil international, who has chalked up eight goals and five assists in Portugal's top flight this term.
Chelsea have been touted as another potential destination for the left-back, although Frank Lampard is reportedly prioritising the signing of Leicester City's Ben Chilwell after conceding defeat to PSG in the race for Telles.
Since arriving from Turkish giants Galatasaray in 2016, Telles has netted 21 times in 183 outings across all competitions for Porto.
