West Ham United will have to make late calls on goalkeeper Lukasz Fabianski and midfielder Lucas Paqueta, as well as winger Maxwel Cornet and defender Nayef Aguerd for Sunday's home clash against London rivals Crystal Palace.
Both Fabianski and Paqueta are doubts with knee and collarbone injuries respectively whilst Cornet hasn't featured for the Hammers since Saturday, October 1 with a calf issue and Aguerd is yet to be included in a Premier League match day squad.
A £30m summer arrival from Stade Rennais, the latter has had a torrid start to life in east London after requiring ankle surgery following an injury sustained in a pre-season friendly against Rangers.
