Brendan Rodgers has admitted Liverpool have defensive problems ahead of their weekend clash with Hull City.
The Reds have managed just one clean sheet all season, and showed their vulnerability from set pieces during the 0-3 home defeat to Real Madrid on Wednesday.
And Rodgers admits it is an area in which the club needs to work on quickly.
“Defensively we need to be better as a team, not just the defence and goalkeeper,” he said.
“We all pride ourselves on clean sheets but we need to be more competitive and aggressive in those moments as a team.
“That was the disappointment against Real Madrid (a 3-0 defeat on Wednesday) and also the goals we have conceded a large number of them have been soft and it is our job to improve that quickly.
“We need to work harder and make it better. We need to reinforce key principles in that organisation and then it’s you as a player on the field showing that competitive spirit.
“The great competitors don’t get done so easily in those situations and that’s something we need to improve upon.”
