The midfielder says Jurgen Klopp was keen to see his side show defensive aggression in his first game in charge.
Many were excited to see how the side would fare under their new manager, with many anticipating him bringing in the style that served him so well with former club Borussia Dortmund.
Lucas started Klopp’s first game and the Brazilian says there were a lot of positives on show from the display.
“It’s a good start. We still have a long way to go but it’s all looking positive,” he told liverpoolfc.com.
“I think for the first game [under the new manager] we could see a lot of positives. Of course with the ball we will get better and be more composed but I think the intensity of our game was a lot higher.”
One area that will need improving under Klopp is the defence, with it being a problem Brendan Rodgers failed to fix during his spell at Anfield.
Saturday’s fixture saw Liverpool keep their first clean sheet in nine games, with central defensive pairing Martin Skrtel and Mahmadou Sakho and goalkeeper Simon Mignolet in particularly good form throughout the game.
And Lucas says that Klopp was keen to see his side show plenty of defensive aggression in his first game in charge.
"The manager wants us to be very aggressive, be on the front foot all of the time and don’t look back and be worried about what’s behind you,” he added.
“Defensively, I thought we were good. Of course they had some good chances but it happens. They have good players and with the ball, for sure we had some good spells and for sure we will get better and understand and learn.”
