Liverpool have turned to the Portuguese market on a handful of occasions in recent years when looking to add to Jurgen Klopp's squad.
Luis Diaz joined the Reds from Porto in January while Darwin Nunez was signed from Benfica in the summer in what could eventually become a record transfer for the club. Diogo Jota, although brought in from Wolves, is a Portuguese international and learned his trade in his homeland, which included a season at Porto on loan.
The latest name to emerge from the Premeira Liga is midfielder Enzo Fernandez, who joined Benfica from Argentinian giants River Plate for an initial €10m in the summer. The 21-year-old is a product of River Plate's academy, having joined the club in 2006, and he made 53 appearances for their first team, scoring 12 goals and registering 10 assists before he was inevitably snapped up by a European club.
