Lucas was part of the Reds' 4-0 win over Everton in the Merseyside derby.
Divock Origi, Mamadou Sakho, Daniel Sturridge and Philippe Coutinho were all on the score-sheet as manager Jurgen Klopp enjoyed a comfortable first derby on Merseyside.
With Everton reduced to 10 men for a Ramiro Funes Mori foul on Origi which saw the Belgian stretchered off, Lucas admitted that the Reds took their foot off the gas a little after they had scored the fourth.
He told the official Liverpool website: "It would be up there as one of the best. When they got the man [sent] off, we controlled the game and looked for more goals.
"At the end we dropped a little bit of intensity but we controlled the game; maybe not the first 10-15 minutes, when they had a few chances on the counter-attack, but after that I think we were better than them.
"I think it's a deserved win. It's special because it's the first derby under Jürgen, we are all happy and hopefully we can keep this good momentum going because we still have a lot to play [for] this season."
It was certainly deserved as there was only one team in it, with Everton failing to register a single shot on target while Liverpool were able to play at their own pace. Barring the injury to Origi, it was as stress-free a night as anyone could have anticipated.
There will be one or two Liverpool fans that wished they had gone for more goals so they could really rub their rivals' noses in it but it is another example of showing just how comfortable things were for Liverpool - and it is hard to think they would not have taken a 4-0 win at the start of the night.
Lucas himself was enjoying a return to the side with Emre Can and Jordan Henderson absent through injury, and played a wonderful ball for Sturridge's strike. The Brazilian will be hoping for more game time between now and the end of the season to impress the manager ahead of the summer and beyond.
