Robertson, 26, is one of the best in the world in his position and helped guide the Reds to Champions League glory last season and the brink of the Premier League title this campaign.
Aurelio told the club's official website: "He's kind of the complete player because physically he's well capable of going forward and going back he defends very well.
"He's quick, so his one-v-one is good and defensively that's very important in the scheme (Jurgen) Klopp plays. He goes forward very easily.
"One thing that calls my attention is that he's always improving, he's not comfortable in his situation being first choice.
"You will see that in every game he plays as his last one, so that's courage.
"The two full-backs of Liverpool right now are unbelievable. We can contest in any kind of way."
