Liverpool defender Virgil van Dijk was delighted with their "clean sheet" for victory over West Ham.
Darwin Nunez scored his first Premier League goal for the winner, while goalkeeper Alisson Becker saved a penalty from Jarrod Bowen on the night.
Van Dijk said: "We got the win, that's the most important thing. We're buzzing with the clean sheet.
"They put four strikers on, Soucek went up top as well and you have to defend as good as you can. We showed that in the last game and again today.
On goalkeeper Alisson after his penalty save, he said: "We play for one of the biggest clubs in the world and to have this goalkeeper with us is something we need and it was a great moment to save that penalty just before the break.
"It is important to keep a clean sheet and a produce a good performance, especially in the first half when we could have scored a second goal. It is all about the three points, especially in this hectic period.
On Liverpool's match-winner Nunez, Van Dijk concluded: "I think he has so much potential. He is still young and he's learning, he's learning the way to play and learning English. He is a modern-day striker which causes a lot of defenders problems.
"You could see today his runs in behind and his build up play getting better. We have different weapons to try and exploit opponents, it is good."
