Serbian midfielder Sergej Milinkovic-Savic has insisted he is happy at Lazio and stressed he does not care as to who comes to watch him in action for the Italian side.

The 22-year-old, who moved to Lazio from Genk in 2015, is attracting interest from the Premier League. According to the Italian publication Calciomercato, Manchester United manager Jose Mourinho is believed to be an admirer of the midfielder, who is valued at €80m (£70.5m, $94.4m).

United have reportedly sent scouts to watch Milinkovic-Savic in action for Lazio. He is one of the most exciting prospects in Italy's top flight club competition. The Serbian international has already scored five goals and registered an assist in the 17 Serie A appearances this season.

Milinkovic-Savic's form has seen him attract interest from Italian champions Juventus and Pep Guardiola's Manchester City. Despite having scouts from top European clubs to monitor him closely, the midfielder stressed that his immediate future lies at Lazio.

"I play for Lazio and I am happy here. These are two important goals, but I play for Lazio and I don't care who comes to watch me," Milinkovic-Savic told Mediaset Premium, as quoted by The Sun.

His rise at Lazio will see his employer demand a far higher fee than what was offered for the midfielder's services in the summer. The Serie A outfit's director of sport Igli Tare confirmed the club had rejected an offer higher than €70m (£61.7m, $82.5m) for Milinkovic-Savic last summer.

"The field dictates his value. We've received offers that are even higher [than €70m], but they weren't from Juventus," Tare explained, as quoted by Forza Italian Football.

"I consider him a player that has ample room for improvement. He will have a great career. He renewed his contract six months ago because he is happy at Lazio, and we hope he can be a symbol for us in the future."

The player's agent Mateja Kezman refused to confirm if there was any approach from the 20-time English champions. However, Milinkovic-Savic's representative stressed their client will not leave Lazio.

"The only person who can act on behalf of Sergej Milinkovic-Savic is myself," Kezman told Tutto Mercato Web.

"Therefore, what I've read is wrong in more than one way and puts unfair pressure on Lazio as it could disrupt the perfect balance in their dressing room, in what has been a magnificent season for both him and the club.

"Has an offer from United actually ar rived? Like I've said a million times already, Milinkovic-Savic is currently not for sale at any price. It's absolutely not the moment to talk about transfers."
