Liverpool legend John Aldridge has slated the team's defending this season.
In his column for the Liverpool Echo, Aldo wrote: "You can argue all you want about zonal marking but there seems to be a lack of belief when it comes to dealing with set-pieces.
"We don't attack the ball, there's no aggression and it is costing us dearly.
"It happened on the opening day at Spurs and it's still happening - we haven't learned our lesson.
"The only way to sort it out is on the training ground. When I was a player if we leaked bad goals we would spend ages in training defending as a unit. The coaches would ensure you didn't enjoy it to ensure it didn't happen again.
"We played pretty well on Monday (against Birmingham) but if you can't defend you aren't going to win games."
