The Argentina international starred for his nation at the World Cup in Qatar, helping the team to their first world title since 1986.
According to O Jogo, Liverpool are lining up a swoop for Fernandez and it is likely the youngster will leave the Portuguese outfit in the summer.
Benfica are holding out for a €120m release clause in the midfielder’s contract, which runs until 2027, and the Merseyside giants have already been linked with a mid-season move.
Fernandez, 21, only joined Benfica last summer and after only 24 appearances, he is being consistently linked with big-money to the English Premier League.
Fernandez has scored three goals and registered five assists so far this season, with two of those goals coming in the Champions League.
