Liverpool captain Jordan Henderson says they must learn quickly from their shock 4-3 defeat at Bournemouth on Sunday.
The Reds twice held a two-goal advantage over the Cherries but three goals in the final 17 minutes saw Eddie Howe's side turn the game around, with Nathan Ake scoring an injury-time winner.
The defeat ended Liverpool's 15-game unbeaten run and prevented them returning to second in the table and Henderson says they must work hard to bounce back against West Ham this weekend, live on Sky Sports.
"That's the one thing you've got to do: try and learn from it as best you can and use it for the next game," the midfielder told Liverpool's website.
"Obviously we'll be disappointed for the next couple of days but we'll get back on the training pitch, get back working hard, and focus on the next game.
"We've been brilliant so far this season but [on Sunday] we weren't at our best and we were punished.
"You've got to give credit to Bournemouth, they kept going right until the end but we've got to learn from it quickly, move on and make sure we're right at it in the next game."

With Chelsea, Tottenham and Arsenal all winning in style over the weekend, the defeat has proved costly in the short term, but Henderson says he is not interested in what other clubs are doing.
"I don't really look at that to be honest," the England international added.
"I've said many a time before, we concentrate on ourselves. If you're concentrating on other teams then you're not focused on what you need to do.
"It's bitterly disappointing today, it's hard to explain, but we just have to move on as best we can and put this one behind us."
