"Of course I was happy to score against Atletico, although I would rather the team have won the game instead of me getting the goal," said Lucas.
"But it was good for me to start and end the pre-season well.
"Sometimes I hear things said about me, but to be honest I don't care too much. I only care about the team and the squad.
"Now I have to focus on the forthcoming season and continue to work hard and improve.
"I will try to prove I have the quality to be in the team and hopefully help Liverpool win the title."
