Jurgen Klopp spoke to reporters at Melwood ahead of Liverpool's meeting against West Ham United on Monday night.
The Reds return to league action as they look to extend their staggering lead at the top of the table with a win against the Hammers.
David Moyes' side visit Anfield in the midst of a terrible run, with the London club failing to win any of their last seven games in all competitions, including a 2-0 defeat to Liverpool last month.
Their last outing saw them defeated 2-0 by Manchester City at the Etihad, however, Klopp insists he saw enough threat for West Ham, which his side will need to be wary of.
“They didn't have [Felipe] Anderson on the pitch and they didn't have [Sebastien] Haller, I know both and I like them a lot,” Klopp said.
“[Manuel] Lanzini was on the bench too so you see the quality they have.
“I watched the game on Wednesday and with all the brilliance we know of Man City, the first goal was a set-piece and the second goal, yes it was a super situation from Kevin De Bruyne but in the end it was a little bit scrappy.
“Bernardo Silva is in the box and then [De Bruyne] takes over the ball, it was kind of a one-two in the box, it was a super goal but they were not outplayed like you would expect when City are on the pitch.
“They fought really hard and defended the box with all they had. I didn't hear what David said after the game but they took some positives out of the game and they will try it again so we have to be ready for that.”
Considering the two sides' recent form, Liverpool are huge favourites to continue their winning streak in the league and get the job done at Anfield.
“It's a night match and we need a really good atmosphere,” he said.
“Not this perception that it will be 1-0 after seven minutes, 2-0 after 24 minutes and it will be easy. It will not be like this.
“West Ham need to fight. They don't have time to waste points. I expect a really tough match, 100 percent.”
