West Ham could face competition for striker target Fyodor Smolov from Real Madrid.
The Spanish side are considering options to bolster their squad and have been impressed by the Russia international's performances in recent weeks for club and country.
Smolov scored twice for Russia in their 3-3 draw with Spain last month and has carried on his rich scoring form with six in his last five games for FC Krasnodar.
West Ham are keen to sign the Krasnodar striker in January and have been pressing for a deal amid increasing competition.
