Liverpool boss Jurgen Klopp has defended his strikers after their midweek defeat at Everton.
Mohamed Salah and Darwin Nunez drew a blank in the 2-0 loss.
Klopp said: "It's tricky. Strikers have to go through these things. That's how it is. That's a striker's life.
"A goalkeeper's life is make 500 saves, then one howler - and everybody talks about this. A striker's life is you score all the time, then you don't score for a while and then everybody asks why you don't score.
"It can be the most difficult thing in the world and sometimes it's the easiest thing in the world, depending on what chance you get.
"We had good chances against Everton but again we were a bit in a rush in finishing them off. So create again, create again and try and get in the right positions to finish the situations off.
"It will be a really rich man or woman who can write that book [on a striker getting back to their best]. You have to go through it. I try to help them speeding it up. That says nothing about the quality of the boys."
On facing West Ham in tomorrow's early kickoff, he added: "They are an opponent who, and I'm not 100% sure, are in a similar situation to us, as they have their lost games... properly. So they want, and have to show a reaction. We want, and have to show a reaction. So let's see who can do this better."
