Croatian striker Marko Livaja – currently with Rubin Kazan – is believed to be on loan at the Irons.
The Rubin Kazan striker joined the Russian outfit last season but struggled to adapt and failed to find the net.
According to reports in the Russian media, Livaja is currently on loan at a team from the Premier League and West Ham is his likeliest destination.
Fellow Croatian Slaven Bilic is familiar with the striker and Russian newspaper Business Gazeta report that a loan move to Upton Park could be on the cards.
Livaja, a Croatian Under-21 international, made his name at Italian side Atalanta.
