Both sides are off the back of Premier League wins, but it can be argued that West Brom’s 2-3 victory over fierce rivals Wolves at the weekend was of greater importance.
The back-and-forth contest at Molineux swung in Albion’s favour as Big Sam secured his first win as Baggies boss, gaining Black Country bragging rights in the process.
The result wasn’t enough to lift West Brom out of the relegation zone, with the Baggies still 5 points from safety – it was, however, a much needed confidence booster.
Meanwhile, West Ham also got the job done in their last Premier League encounter with a narrow 1-0 victory over Burnley at the London Stadium.
The Hammers lack of a striker is a cause for concern, with Michail Antonio the only fit centre forward in David Moyes’ ranks after the sale of Sebastien Haller to Ajax earlier this month.
West Ham didn’t appear to struggle to create chances against Burnley but finishing them off did seem to be a bit of an Achilles heel.
A win for the Hammers will take them up to 7th place – leapfrogging Chelsea in the standings who play Leicester later on Tuesday night – whilst going level with 6th placed Everton.
3 points for West Ham will need to be secured without the defensive services of Fabian Balbuena, who is self-isolating after coming in to close contact with an individual who has tested positive for coronavirus, whilst fellow defender Arthur Masuaku remains a long-term injury absentee.
Aside from that David Moyes has a relatively clean bill of health.
Sam Allardyce does have fitness issues at West Brom meanwhile, where impressive goalkeeper Sam Johnstone will be absent due to contracting Covid-19, as will teammate Matt Phillips who has also tested positive for the virus.
Midfielder Conor Gallagher is available again for the Baggies after serving his suspension last time out against Wolves.
Grady Diangana is rated touch-and-go to feature against his former employers as he continues to recover from a muscle strain which kept him out of the Black Country derby.
West Ham v West Brom is a 6pm kick off on Tuesday, 19th January.
