Sergej Milinkovic-Savic's agent Mateja Kezman insisted the Lazio midfielder is not for sale at any price, though he refused to deny whether Manchester United have made an offer.
Milinkovic-Savic has emerged as one of the most sought-after players in Europe, with Premier League giants United, Manchester City and Juventus linked with the 22-year-old star.
Speculation continues to mount over a possible move to Old Trafford but the Serbia international, who signed a contract until 2022 last April and has already scored three Serie A goals this season, is not leaving Lazio.
"The only person who can act on behalf of Sergej Milinkovic-Savic is myself," former Chelsea forward Kezman told Tuttomercatoweb.
