The Hammers have reportedly moved ahead of London rivals Tottenham in the race to land the 23-year-old this summer.
Linked with a move since January, the Irons could be set to finally land their man as Spurs edge towards a move for Atalanta ace Cristian Romero.

READ WEST HAM VERDICT
Valued at £22.5millon despite a dwindling contract (Transfermarkt), singing Milenkovic for the mooted £13million fee would be a bargain buy.
As other reported targets such as Kurt Zouma could potentially cost double that amount, the Serbian has to be the priority at the London Stadium.
Unsurprisingly an aerial threat, adding Milenkovic to Tomas Soucek, Craig Dawson and Declan Rice would pose an ominous sight for opposition defenders.
