The Dutchman did well in the left-back position and relished the chance to play in front of such a vocal crowd.
"It's good for me to play these games," he said. "It's a good level and I can see where I'm at. It was a good game and I felt I did well."
Büttner admitted there was added determination in the home dressing room to win on Wednesday given the result in the weekend's Manchester derby.
Losing so comprehensively to Manchester City hurt everybody at the club and fuelled the Reds' desire to bounce back against Liverpool.
"It was an important win. Everbody wanted to win because of what we saw in the last game. We played as a team today and you could see on everybody's faces that we wanted to win.
"Everyone knows about what happened in the last game. The result was not good and we know we have to fight if we want to win games. Today, you saw people running in the last second of the game. We played well today."
