West Ham United manager Slaven Bilic
Ravaged by injuries, Bilic will have to patch together a side for the game at the Stadium of Light.
But a risky decision he made in the 1-0 victory over Swansea City last time out could be very bad news for Sunderland.
Sakho is working his way back from almost a year out of action - bar some minutes during his ill-fated comeback in November - while Carroll has nursing a sore groin.
Both could have been used against Swansea had they been needed but Bilic's side managed to get through the game without doing so which means at least one if not both could feature against Moyes' strugglers.
Sakho and Carroll should both be fit to face Sunderland
Sakho is reportedly champing at the bit to start and Bilic has had to hold him back for his own good.
And another week of treatment on Carroll's groin should mean he is fit to at least make the bench again if not start.
The big former Newcastle United star has a good record against his boyhood club's hated rivals and Carroll will undoubtedly be keen to be involved.
With Michail Antonio injured it will be a major boost for the Hammers and worrying for Sunderland who already have enough to worry about.
