"It was incredible to be at the stadium on Sunday," said Aquilani.
"It was one of the best games I have seen so far. I don't normally like to watch a match inside a stadium when I am not playing, but I really enjoyed Sunday.
"When I was in Rome, although the stadium was bigger, it did not have the same atmosphere as here. Because the fans are closer to the pitch at Anfield, you can feel the atmosphere better.
"It was very important to win against United and hopefully it can give us more confidence."
