West Ham United have submitted an opening offer to Fiorentina for defender Nikola Milenkovic.
According to Football Italia, the Hammers are very serious about signing the Serbia international.
They have put in a bid of €15.5 million to convince his Italian club to sell.
Manager David Moyes has made Milenkovic his primary target to shore up his back line ahead of next season.
West Ham will play Europa League football, which should attract a player such as Milenkovic to sign for the Premier League club.
