"It's always nice to score a goal, and it was a good goal and a good win for the team, so I'm happy about that," said Lucas.
"We know we have to work hard in pre-season because we have a long season ahead and we are trying to put the things we are doing in training into practice in the matches.
"The manager has given me more freedom to go forward and that suits because that is my style.
"I think my form and fitness are improving every day even though it has been tiring because pre-season has been hard but I am happy with my goal.
"I am confident that I can score more goals. Last season I got only one but in Brazil I scored quite a few so I have the belief that I can score more for Liverpool."
