At the start of the season nobody would have expected Barcelona to end up with a defence reading: "Jordi Alba, Oscar Mingueza, Frenkie de Jong and Junior Firpo."
However, that's how they ended their 4-0 win over Osasuna at Camp Nou. Firpo was at right back, Oscar Mingueza and De Jong in the middle and only Jordi Alba providing a sense of normality at left back.
Mingueza until a few days ago had not made his debut, De Jong usually operates in midfield and Junior is on his way out of the club.
Clement Lenglet suffered an ankle injury in the second half and had to go off, forcing De Jong into the back line. Gerard Pique is out, Ronald Araujo still has not recovered and Samuel Umtiti is permanently in the treatment room.
