The Reds lost 3-1 at Anfield against Chelsea in the first leg of their quarter-final.
Aurelio told Sky Sports: “We cannot let it [the loss] affect us. We have been playing really well and the team has been really confident.
“For sure, the result has been a disappointment. But we know that we still have a chance.”
Midfielder Lucas Leiva added: “We know that it is going to be really difficult, but not impossible. We now have to think about the Premier League, and then the second leg.”
