Barcelona has not lost to Atletico Madrid at Camp Nou since February 5, 2006, accumulating 18 wins and seven draws in that span. Despite their poor Champions League record against Atletico, the Catalans have the momentum after beating Diego Simeone's men in their most recent encounter.
Atletico holds the advantage of better-rested players, with Simeone having kept his starters fresh for the crucial European tie. Flick's Barcelona will look to dominate the first leg at home before traveling to Madrid for the second leg next week.
