Liverpool legend Ian Rush has claimed that the Reds must learn how to keep clean sheets if they are to challenge for honours this season.
Jurgen Klopp's side have struggled defensively at the start of the season, having already conceded 11 goals in six games in the Premier League.
"We have to learn to keep clean sheets," Rush told Sky Sports News on Thursday.
"At the end of the day, attacking wise, we have 20, 40 minute spells where we're absolutely unbelievable - we can beat anyone in the world.
"It's not for the lack of chances but we're not putting them all away. When you're playing the top teams, if you're not careful you get found out.
"We've got to start learning how to keep a clean sheet because we're not going to score every game. We have to learn to stop it at the back and if we can do that I think we will be alright."
Up next for Liverpool is an away fixture at Newcastle United on Sunday.
