Brendan Rodgers was right to point out after the game that Liverpool had conceded acres of space to Cardiff by sitting too deep which led to the Welsh side's first two goals.
Whether this was a one-off scenario isn't so certain however. For anyone that has watched Liverpool play since Steven Gerrard's reinvention as a holding-midfielder it would be remiss not to acknowledge his responsibility in the Reds' defensive woes.
Playing in a deeper position he is supposed to protect the back four. Unfortunately for Gerrard he didn't do that on Saturday and it's not the first time that can be said.
While the immediate thing to notice was how much space Jordon Mutch found himself in as he collected the ball before running infield at Daniel Agger, and unleashing a curling effort that nestled into the net, it was more instructive to note just how deep Liverpool's defenders were stationed.
To observe Martin Skrtel, Jon Flanagan, Glen Johnson and Agger encroach further and further onto Simon Mignolet's area the more the replays of the goal was perplexing and how more so for Rodgers.
The consequences of all this of course was to leave a huge gap between the midfield and defensive lines and Mutch made Liverpool pay.
What proved even more baffling was that lesson were not learned, Fraizer Campbell's goal coming some 16 minutes later from exactly the same situation.
In mitigation perhaps Campbell and Craig Bellamy's pace on the break was a concern for the Liverpool's defenders which saw Agger et al stay on the edge of their box and thus allow the pair to run at, rather than in-behind, them.
Perhaps not. To go back to Gerrard, he found himself far too up the field on both concessions, and therefore unable to do his job acting as a shield for the back four.
Hardly surprising then that they should be left completely exposed, particularly Agger for the second, and unable to prevent the inevitable.
Either way Liverpool will need to address how they set up to deal with pacey frontman and reassess Gerrard's role at the base of midfield. That or they will have to settle on outscoring their opponents each and every time. Whisper it quietly but maybe some Liverpool fans are happy with that if it's all in the name of entertainment coupled with results. Not good for the heart though!
How worried are you about Liverpool's defence and will it be enough of an issue to prevent them from winning the Premier League?
