Boss Jurgen Klopp insists he is fully aware of his Liverpool side’s shortcomings when defending set-pieces in the wake of Saturday’s 5-4 victory at Norwich.

The Reds needed a last-gasp Adam Lallana strike to take all three points away from Carrow Road following a roller-coaster Premier League clash in East Anglia.

The Canaries thought they had done enough to earn a point on home soil before the England star came off the bench to settle the encounter in the visitors’ favour.

Liverpool’s win was not enough to mask their problems at the back, with only lowly Bournemouth and Swansea conceding more goals from dead-ball situations so far this season, and Klopp knows his players must tighten up.

“First of all, of course we know about this problem. I am sorry to say it is not a problem we can ignore,” the German said. “It is obvious we didn’t handle it too well. We are a football team and we always work on our weaknesses.

“It is not about the formation because we changed the formation. It is not always about the quality of the set-plays – it is about what we are doing.

“We had good talks together – it’s not the first one but hopefully the last one. It is not too late to learn, but now it is time to learn and show we have learned.”

Liverpool’s weekend win saw them climb up to seventh place in the Premier League and they are now 4.50 for a top-four finish this season.
