Former Liverpool striker John Aldridge has said the side must sort out their troubles from set pieces after it cost them against West Bromwich Albion at Anfield on Sunday.
The Reds were undone by two set pieces in a 2-2 draw as familiar errors came back to haunt them and Aldridge wrote in his Liverpool Echo column that if the Reds are going to overcome sides like West Brom then they must address their defending from corners and free kicks.
He said: "If we’re going to overcome sides that set up like that then we’ve got to defend these set pieces so much better. We’ve have to treat opposition corners as if they were our own corners, busting a gut to attack the ball and getting it clear of danger.
"Much more collective desire is needed for me - probably much better communication, too.
"I’m sure the manager will be working on it all at Melwood in training because it simply has to improve. You can’t be caught flat footed like that. You can’t just allow people free headers."
It is certainly something Liverpool have struggled with for a number of years now and one that Klopp needs to get to grips with as soon as possible.
It needs to start with the goalkeeper, who must take a lot of responsibility for the way the first goal came about, even if Klopp wants to take the responsibility himself, while for the second goal at the weekend it was perhaps just a case of a really good delivery outdoing the Reds, but even then the marking could be looked at!
A lot of it comes down to certainty and there does not seem to be too much of that among the Liverpool back-line at the moment. Klopp has a little bit more time ahead of the next two games to work on things on the training ground.
He might have to do it without Dejan Lovren who was stretchered off during Sunday's game, with Aldridge saying: "I feel a bit sorry for Dejan Lovren too. He has looked a bit more settled recently after a run of games, but he now could be out for a spell."
It looks certain that Mamadou Sakho will be thrown back into the action on his return from injury, but Lovren has at least looked a little more assured, even if there are times he can look a little awkward and may produce an error, there have not been anymore huge gaffes that have become common place during his Liverpool career to date.
