Liverpool visit bottom of the table Portsmouth in tomorrow’s lunchtime kick-off, having won just four times in the last 16 games.
And Lucas hopes the 2-1 win over Wigan on Wednesday will spur the side on to a successful festive period of results, in which they face Portsmouth, Wolves (Boxing Day) and Aston Villa (28/12).
He said, “We could feel the taste of victory again in midweek which was really important after the defeat by Arsenal.
“It was an important win for us as we want to be as close as possible to the top four. We have to fight for every point and each game left for us will be like a final for the rest of the season.
“We are working really hard and hopefully the second part of the season will be even better. We have to think about each game and win some games in a row. That will give us a lot of confidence and I have confidence we will finish in the top-four.”
