The agent of Sergej Milinkovic-Savic has confirmed that he received a number of "huge bids" for his client.
The Serbian is a target for a number of Serie A clubs as well as Premier League champions Chelsea.
But Mateja Kezman says the 22-year-old is in "no rush" to leave Lazio and that he will stay in Rome at least for one more season.
"I've received huge bids, over €50m in the past few weeks," Kezman told Calciomercato.com.
"As we agreed at the start of Sergej's contract though, he's not for sale this summer. He's very happy at Lazio and wants to help the team fight for a place in the Champions League next season.
"After that, you can never 100 per cent know what will happen in life…
"We're in no rush, the lad is happy at Lazio, he's growing and [coach Simone] Inzaghi is doing good things with him.
"He's only 22 and next year we're expecting to do great things with the Biancocelesti."
