I guess we are good with squad depth this season. The only problematic position I can see is the midfield - in case 2 of 3 starters get injured simultaneously. But none of them is injury-prone, so let's hope no serious injuries will happen.
GK - MATS, Pena, Tenas
LB - Alba, Alonso, Balde
CB - Kounde, Araujo, Garcia, Christensen, Pique
RB - Bellerin, Roberto, Kounde, Araujo
