Liverpool may have comfortably won 3-0 over Maribor in the Champions League on Wednesday night, but victory did little to paper over the cracks.
Goals from Mohamed Salah, Emre Can and Daniel Sturridge secured all three points at Anfield to ensure they remained top of Group E.
Despite being top, Liverpool's place in the last 16 is far from certain, with Sevilla breathing down their necks in second and Spartak Moskva still in with a chance.
They travel to Spain to face Sevilla in two weeks' time, which could well determine who finishes top of the group, before hosting Spartak.
Scoring goals certainly hasn't been a problem for the Reds, having notched 13 so far, but defensively they continue to cast doubt.
Away from Europe, Liverpool have conceded a number sloppy goals this season and currently boast the sixth-worst defensive record in the Premier League (16).
The vast majority of the goals scored against Jurgen Klopp's side have been the result of individual errors, hence why they've only won four games and are currently 12 points off the pace.
Against Tottenham recently, for example, each of the four goals Liverpool shipped came after some woeful defending from the likes of Dejan Lovren and Joel Matip.
Simon Mignolet was also at fault when he flapped at a corner and watched helplessly as Harry Kane scored his second of the game.
Change is needed and it's down to Klopp to identify what's wrong, especially considering it was his decision to not sign any new centre-backs over the summer.
However, according to Liverpool great Sami Hyypia, the problem at hand is obvious.
Hyypia is regarded as one of the Liverpool's greatest ever defenders and speaking on BT Sport, he hit the nail on the head by explaining what's missing: communication and leaders.
HYYPIA NAILS LIVERPOOL'S DEFENSIVE WOES
Hyypia said: "There's a lack of communication. They're not doing it together. There's many situations that the centre-backs or defenders don't know who is going and who's taking the ball.
"That's about communication. I see that might be part of the problem. There's not enough leaders in the team. Somebody needs to take charge on the field and talk.
"Of course, communication is everyone's responsibility, but you can do it together."
Well said, Sami. Liverpool's defence lacks leadership and because there's barely any communication, goals are being leaked far too easily.
Liverpool fans wholly agreed with Hyypia's comments on BT Sport and want him to return as a defensive coach. Here's how Twitter reacted.
