Telles, who reportedly has a release clause of £35 million, has been a Porto player since his switch from Galatasary in 2016 for £5.7 million and has gone on to make 62 appearances for the club.
Despite a decent stint for the Portuguese team, the 25-year-old had a far less successful time for Galatasary who loaned him out to Inter Milan.
Inter Milan were equally unimpressed with Telles and decided against making his transfer permanent.
However, Telles seems to be much improved in Portugal and has reportedly caught the eye of Jurgen Klopp and Liverpool who are keen to strengthen in the full-back areas.
