Atletico Madrid goalkeeper Jan Oblak made three outstanding saves in mere seconds to keep Bayer Leverkusen scoreless in a must-win second leg for the Bundesliga outfit.
Down 4-2 on aggregate, Leverkusen came into Wednesday's reverse fixture in need of a convincing win.
But Oblak has offered a strong resistance in Europe, conceding just two goals over his previous six Champions League appearances, and popped up again and again to stifle Leverkusen's attempts.
