Gerard Pique has been on a downswing for a while.
Barcelona have bought two left-footed centre backs this summer in Thomas Vermaelen and Jeremy Mathieu.
The former is out injured at the moment so the latter has strolled into the team and taken the left-sided spot in the middle of Barca's back four.
Javier Mascherano started the season in the right centre-back role, but was sent off against Elche in the first match of their La Liga campaign.
That means that either Marc Bartra or Gerard Pique, who was suspended for the first game, will step in alonside Mathieu against Villarreal on Sunday.
Although Pique had been a fitness doubt, as alluded to by Spain manager Vicente del Bosque when he axed him from his latest squad on Friday, as per ESPN.co.uk, he has been training as normal with Barcelona.
Which of the two Luis Enrique selects will be interesting.
If it is Bartra, people will say it displays his commitment to youth players. If it is Pique, then perhaps Enrique thinks he can restore the defender, who was out of sorts last season and endured a miserable World Cup, to his best.
This season the coach has to decide how much game-time he wants to give each of the two players.
With Mascherano also an option, he could snub the call and keep the Argentine there, even though he prefers to play in midfield.
