The 22-year-old has recently finished his most productive season to date, scoring 32 goals in Portugal’s top flight and the Champions League.
Nunez is now anticipated to join a larger European club in the coming week, with teams from the Premier League and around Europe keeping an eye on the issue.
According to FootballTransfers, agents of the Uruguay international have been in talks with a number of English clubs, including Liverpool and Manchester United.
Although Nunez is reported to prioritize remaining in the Champions League, the report claims that he could be enticed to move to Old Trafford.
Newcastle United and Tottenham Hotspur are also said to be interested in the midfielder, though it remains to be seen whether they are capable of competing with their fellow Premier League clubs.
