West Ham are facing an injury crisis with Manuel Lanzini and Marko Arnautovic having both succumbed to hamstring injuries.
It comes after manager David Moyes has had to navigate his way through a hectic schedule with what he feels is a small squad.
The injuries to Lanzini and Arnautovic come as a huge blow as the Hammers aim to avoid dropping down to the Championship.
Lanzini was forced off during their 1-1 draw with Bournemouth at the weekend and he is set to be sidelined for more than a month.
