My mate sat next to me at this game said we are playing diamond (Vs Red Star at anfield). Fab was holding, gini and mane either side of midfield, with Shaqiri behind Salah and Bobby. I didn't see it myself, but he was adamant that was the system we were playing.
Strange because Klopp himself said we were playing a double ‘6’ system with Gini and Fabinho i.e. the inverse triangle as my son calls it with Shaqiri in front of the other two. That makes a lot more sense to me because it compensates for Shaqiri’s defensive issues.
