The agent of Benfica striker Darwin Nunez - linked with moves to the two Manchester clubs - has claimed that contact has been made with "top-level teams".
The 22-year-old has enjoyed a prolific two years under the tutelage of Jorge Jesus, scoring 20 goals and setting up 12 more in 52 appearances for Benfica across all competitions.
Manchester City and Manchester United are believed to be keeping tabs on Nunez's development, and the striker's agent Edgardo Lasalvia has confirmed that discussions have been held with world-class clubs.
Speaking to FC Inter News, Lasalvia said: "Darwin is ready to play in any team on the globe. Various top-level teams have contacted us, but for the moment the head is on continuing and growing with Benfica and with the Uruguayan national team: this is how important things will come.
"The important thing is that he is happy now and wants to repay the trust of Benfica and the affection of the people by winning a title. We'll discuss the transfer possibilities with the club executives if necessary, as it should be. For the moment we're calm and happy to see him on the pitch."
Nunez already boasts six goals from eight games this season, including a brace in his side's 3-0 Champions League win over Barcelona last week.
