Premier League leaders Liverpool head to the London Stadium on Wednesday night to face a West Ham United side scrapping to stay out of the relegation places.
The Hammers are currently hovering just above the drop zone in 17th place - ahead of Bournemouth and Watford on goal difference - but would give themselves breathing space on their rivals with a positive result against the Reds.
David Moyes, who steered the Hammers out of the bottom three and to safety during a six-month stint in charge during the 2017-18 season, replaced Manuel Pellegrini at the end of December and has taken four points from four games since his return.
