West Ham have been linked with over 30 players in the January transfer window.
The congested nature of the top flight means the East Londoners are far from safe, though, and injuries are starting to take their toll.
David Moyes has publicly stated he needs to bring in at least two players this month and that is becoming more acute by the day with a glut of injuries to key players.
Moyes is desperate for more quality in midfield and players who can look after the ball better.
The Hammers have been linked with the likes of Deulofeu's Barca teammate Andre Gomes, Jonjo Shelvey, Joe Allen, Joao Mario and Steven N'Zonzi to fill that role.
El Gol Digital claims the Hammers are willing to pay £20 million for the playmaker.
Deulofeu would be an ideal replacement for Lanzini who has been ruled out for the most important month of West Ham's season with a hamstring injury.
