After only being used as backup by Jurgen Klopp, Lucas decided to leave Anfield having made a total of 345 appearances during 10 years on Merseyside.
Lucas has since established himself as a regular with Lazio, and the Brazilian has admitted that he is relishing the opportunity to take on a fresh challenge.
The 30-year-old told Di Marzio: "After 10 years in Liverpool I was looking for a new challenge. The team, the league and the city had all an impact on my decision to come here. I still have many friends in Liverpool, including Steven Gerrard. He was an amazing footballer and he taught me a lot as captain.
"Now I am here and I settled in quickly. That's because I came in an organized team, where almost everyone already knew each other."
Lucas has made 10 starts in Serie A, while Lazio currently sit in fourth place in the standings.
