Liverpool defender Martin Skrtel says they must not relax against Cardiff City this weekend.
Skrtel insists Liverpool must match the heights reached at Manchester United on Saturday afternoon when they travel to south Wales to face Cardiff.
"It was a wonderful match - one that I will always remember," said Skrtel.
"We were really good and nearly perfect. Obviously it is a place where it is never easy to win, so I am really happy.
"We scored three times and we could have scored even more. We also controlled the possession so this time we can say that we are really satisfied.
"I am also happy that we kept our clean sheet. Now we must show our improvement against Cardiff."
