Fiorentina coach Vincenzo Italiano is eager for Nikola Milenkovic to stay.
The Serbia defender is being linked with a big club move away.
Italiano said: “I hope that Nikola will remain a Fiorentina player.
"It's not easy to find someone so clearly enmeshed in our idea of football, he's a great professional and if we were to bring someone else in, it would take time to get him up to speed.
“This is a top level player who will be at the World Cup, so I hope he will remain with us."
