Liverpool defender Jamie Carragher has urged the team to rise to the challenge of losing captain Steven Gerrard for up to a month.
Scans on Thursday revealed the Reds skipper had sustained a grade two hamstring tear in England's friendly defeat to France on Wednesday, having played 25 minutes longer than agreed.
"There is no doubt Steven will be missed whether we win, lose or draw because he is such an important player here," Carragher told the Liverpool Echo. "But it is up to us to perform well and lessen the impact, like when we beat Spurs (2-0) in January without him and Fernando (Torres)."
He added: "There are a few similarities because that game came a few days after a disappointing result against Stoke when we drew 1-1 but we showed we could bounce back.
"Everyone knows what great quality Steven has and it is frustrating for everyone - though nobody more than him - that he is out because he has been in such good form.
"But the most important thing now is beating West Ham. We know we didn't perform at Stoke but if we get three points tomorrow, the league table will look much better and we can push on."
There has been some good news on the injury front, although the return of defenders Glen Johnson and Fabio Aurelio hardly compensates for the loss of Gerrard.
Johnson has been out for three games with an adductor strain while Aurelio, who has struggled with Achilles and groin injuries, has made just one 25-minute substitute appearance since August 26.
"It's nice to have some good news," said Dr Peter Brukner, head of sports medicine and sports science.
"Fabio's worked incredibly hard. I think we all know he's had a horrendous run with injuries in the last two or three years and he got injured again a few weeks ago. He's worked very hard to get himself right. He's trained for the last week or so and played the majority of the reserve game on Tuesday, and I'm happy to report that he's come through that well."
