In fact, we are still a bit short in defense because our left footed CBs were also supposed to be partly backups for Alba too. The Barca B players are obviously not good enough. If Alba gets a lengthy injury spell, I guess its Lenglet or Roberto at LB.
Don't remind me with that LB situation, I still don't get what Abidal was thinking when we entered the season with that defense.
Back up LB is likely going to be (in on order):
-Vermaelen (in the 4 weeks he is gonna be healthy in the season).
-Wague/Miranda. The former is RB but comfortable in LB position too and far more experiences than Miranda, so I suspect he might play the position.
-The veterans (Lenglet/Semedo/Umtiti/Roberto)
-343 like we used with Semedo & Roberto out.
