The Reds are now finally in the top half of the Premier League after 11 games and the manner of their 2-0 Anfield success over the champions is sure to breed confidence.
Double goalscorer Fernando Torres will also hope his performance signals the start of an upturn in fortunes after a dismal start to the campaign.
And for Lucas too, the match could mark an important staging post in his Anfield career.
The much-maligned 23-year-old Brazilian produced one of the best performances of his three years at Anfield with a bustling all-round display.
Lucas said: "That will give us a really good mood and we will try to keep the same levels of performance.
"I think we believed in our team, that was the main thing.
"We played with intensity, everyone could see how intense all the team played.
"I am getting older and I think I am getting better. When you get more experienced you feel important and you want to do more.
"In the last few games I have been really pleased with the way I am playing.
"The team is winning and when the team is winning everyone has a better performance."
Lucas was often given a holding job by former manager Rafael Benitez.
That was perhaps not his preferred position but he now feels he has matured and is able to play a role that contributes in both defence and attack.
He said: "It is good to see Brazilian players are not just tricks and you can do a 'dirty' job for the team.
"That is what I am trying to do, to do the job defensive and try to get forward when I can.
"As a player I am trying to be consistent. This season I am getting better, I will just keep the same level and try to be in the team all the time."
Liverpool were in the bottom three just over a week ago but are now looking upwards after three successive victories.
They will now look to maintain their revival as they make the short trip to Wigan on Wednesday.
Lucas added: "We are happy but of course we are still not in the position we want to be.
"We want to be higher in the table but we have to keep going."
