West Ham United are eager to sign Fiorentina defender Nikola Milenkovic this summer.
The 23-year-old is being linked to the London side by Sky Italia.
The Hammers are close to making a firm offer for Milenkovic, but are aware that Fiorentina are willing to sell.
David Moyes wants another centre-half, with his current options being Issa Diop, Angelo Ogbonna and Craig Dawson.
If Milenkovic were to sign for West Ham, he would likely become first choice at the start of the season.
