"Of course it's going to be difficult but I will be trying my best [to get a regular place in the starting line-up ]," said Lucas.
"We had a good second half of the season but we didn't win the title. Hopefully this year we can win the title and this is our challenge now.
"I think that winning the league is most important because it's been an 18 year wait since we last won it.
"The focus is to win something but the most important thing now is the Premier League.
"Of course Liverpool would have wanted me playing in Liverpool because I will miss some games - some important games - but they know that [the Olympics] is important for me and for the country.
"Hopefully, we will win this title and then I can return to Liverpool and think about the Premier League, the Champions League and the other cups."
