Aurelio said: "If you look at the last few Champions League campaigns, Liverpool have been in the last four consistently.
"And we have reached two finals in recent seasons. Where were Madrid? They are a great club with great history in Europe, but Liverpool are also famous in the competition."
Aurelio was one of seven players in Liverpool's starting line-up in the Bernabeu who have faced Real in La Liga.
And the confident performance, somewhat out of keeping with recent Premier League displays, produced a deserved first-leg win to stun the vast Spanish audience.
And Aurelio said: "We are not frightened of anyone. Certainly, from my point of view, I am used to playing against Real every season from my time in Spain, as are many of our players.
"But aside from that, we are Liverpool, and we do not have to be afraid of anyone. And the draw we achieved in Madrid certainly excited all of our players."
