And in all these it was Ronaldo playing on the opposite side. Only time they lost a european KO tie vs a team not featuring Ronaldo was 2013 vs Rubin. They won their other 2 EL campaigns and as you mentioned lost to Real/Juve in the CL every time. Quite impressive
They did crash out in the group stages against Roma and Chelsea though. Also, this Atleti team is nowhere as good as it used to be. That said, I hope they beat Liverpool.
