Arsenal manager Arsene Wenger looks set to be without Tomas Rosicky (calf) and Lukasz Fabianski (ankle) but Andre Santos could be fit and available for selection after being sidelined with an abdominal injury. Mikel Arteta (calf) has an outside chance of returning, but may not be risked.
Ivory Coast forward Gervinho will be absent due to his presence at the African Cup of Nations, while Abou Diaby will be closely monitored prior to kick-off.
West Ham boss Sam Allardyce rested Carlon Cole for the weekend's game against QPR but looks certain to return him to the starting line-up, with Marouane Chamakh, on loan from Arsenal, unavailable for the fixture against his parent club.
Elsewhere, both Andy Carroll and George McCartney miss out with knee injuries for the Hammers away trip to the Emirates Stadium, with James Collins still a doubt with a hamstring strain. Forward Modibo Maiga is also at the ACN with Mali.
