After some indifferent form, the Gunners made a statement in the title race by beating Liverpool to put themselves right back into the mix, though they cannot afford too many more slip-ups.
While they will be favourites to beat David Moyes and his side, the Hammers defeated Arsenal at the London Stadium earlier this season when the two sides met in the Carabao Cup, while they also won at the Emirates in the league in December.
