The 25-year-old was heavily linked with Spurs in the summer, with the player even revealing that terms were agreed over a move to North London before his club blocked the move.
According to Portuguese outlet A Bola, Mauricio Pochettino’s side have not given up hope on bringing Fernandes to North London with the club’s interest still very much apparent.
The newspaper adds that if Christian Eriksen – who continues to be linked with a move to Real Madrid – leaves the club, then Spurs have all the more reason to finance a move for Fernandes.
One recent report suggested that Fernandes is valued at around £61m by Sporting, meaning Eriksen’s departure could be the key sticking point if Daniel Levy is to give the green light on an approach for the Portuguese.
Tottenham have started the season in mixed fashion, with Pochettino claiming that the fact that the European transfer window was open until September 2 caused anxiety among his squad.
The club sit in ninth in the Premier League table and face Watford upon their return from the international break.
