The question mark that hangs over the stability and ability of Barcelona's defence is once again threatening to overshadow their start to the new season.
For a club that is so rich in midfield and attacking talent, the perennial struggle in certain areas of defensive play and the difficulty in finding a commanding centre-back are a mystery to many.
Dmytro Anatoliyovych Chygrynskiy was touted as the heir to Carles Puyol's throne as far back as 2009, and the €25 million invested in his subsequent capture convinced many at the time that the defensive frailties were a thing of the past.
The less said about that experiment, the better.
Various personnel have come and gone, and many have been utilised in positions that, while not exactly alien to them, are certainly not their natural habitats.
Let's take a look at who might populate Barcelona's back line in the 2013-14 season.
This list will only include playing staff currently on the roster at Camp Nou, not the never-ending list of targets who may or may not arrive during the summer transfer window.
