Liverpool take on Atletico Madrid at Anfield on Wednesday night and if previous meetings between the two clubs are anything to go by, the away side will be met by a raucous atmosphere.
It is a trip into the unknown for Andoni Iraola as he prepares for his first-ever Champions League match as a manager. Before Liverpool came calling, he might have expected to be playing in the Europa League having qualified old club Bournemouth for that competition last season.
