Liverpool boss Jurgen Klopp says victory over West Ham should not be underestimated.
Mohamed Salah's penalty was canceled out by West Ham's Jarrod Bowen before Darwin Nunez and Diogo Jota settled the game 3-1 for the Reds.
Klopp said: "In moments very good. Tough opponent. I had a long talk before the game with David [Moyes], fantastic guy.
"It's obvious how good a team or squad West Ham has now and they can cause each team problems. They did it with us today. We tried to control the game and create chances and that's pretty tricky you have to be consistent to deal with setbacks.
"Super goals. Love them and really really good performance and mature performance.
"That's it, really happy for today."
