After two league defeats it was vital Liverpool got back on track against Wolves at the weekend and their 2-1 win did just that says Lucas.
"It was an important win," said the Brazilian.
"It was a heavy defeat at Spurs, so it was important to win in the Carling Cup and get three points in the Barclays Premier League which gives us the chance to be closer to the top four.
"We spoke before the game against Brighton. We needed to win, get back on track, go into the next round and come into this game with confidence - and to win too. That is what happened.
"It was a tough game and we had plenty of chances but only took two.
"It is hard when you concede a goal early in the second half. We tried to control the game and I think we managed well.
"I think sometimes we are a bit unlucky; we twice hit the post and there were a couple of saves by the 'keeper but that means we are creating chances.
"If we can score more goals it will be good but it was an important win."
