The Nigerian striker has spent his entire senior career in Italy, coming through the ranks at Spezia and spending time on loan at Cosenza. He also has represented Nigeria at U23 level.
Spezia are currently preparing for their Serie B play-off campaign after finishing sixth in the league. They face Cittadella on Friday as they bid to reach the top-flight.
But if Spezia remain in Serie B, Okereke could be tempted by a move to England. West Ham could offer him Premier League football.
According to transfermarkt, Okereke’s contract lasts until 2022. But could he be West Ham’s striker for the future?
