Madrid defender Sergio Ramos was fortunate not to be penalized for unleashing an elbow into Mario Mandzukic's eye in the penalty area shortly afterward. The Croatia forward had to leave the field three times to receive treatment on a bleeding eyebrow.

After that, Madrid sustained increased pressure as Atletico launched several attacks.

Madrid missed a clear chance when striker Karim Benzema chose to pass to Bale instead of shooting, with the Welshman's shot being blocked by Diego Godin in the 69th minute.
