Lazio midfielder Sergej Milinkovic-Savic is attracting huge interest from abroad, says his agent.

He has been linked with the likes of Real Madrid, Paris Saint-Germain and Manchester United in recent months, while Lazio claimed on Sunday that they had rejected a €70m bid from an unnamed suitor for the Serb.

“There's huge interest in him from great clubs in Italy, England, Spain and France," Mateja Kezman told Tuttomercatoweb.

“I don't want to talk about numbers, but I'm sure Sergei has it in him to be the best player in Europe in the next few years.

“Still, we'll talk about transfers at the end of the season, Lazio, for now, are playing great football and having an important season. We're all focused on this.

“Where has he grown? In everything: from the mental point of view, but also physical and technical. I see him grow every day in every sense.

“Can he improve on anything? I repeat, he's a player who has no limits. He can grow in every aspect.

“Will the World Cup take him to the next level? He'll play in it with his country, and this is a great responsibility and honour for him."
