The Reds face an uphill task to continue in the competition as they head into the second leg of their last-32 clash with Zenit St Petersburg at Anfield trailing 2-0 on aggregate.
But the five-times champions of the continent have produced many of their most celebrated European victories under the Anfield floodlights and with the crowd at their most passionate, and Lucas wants to see it again.
Echoing similar rallying cries by team-mates Steven Gerrard and Martin Skrtel, the Brazilian said: "It is a competition we always wanted to do well in.
"We always know on these special European nights at Anfield what the crowd give to us.
"It will be an important game for us this season. We are really positive and believe we can get through the next stage.
"Hopefully the crowd will give us a special night and we will play well and get through. The crowd will definitely be our 12th player."
