Watch: Real Madrid rocked by Chelsea's Rudiger

Uh oh, Real Madrid.

Chelsea erased a two-goal deficit at the Santiago Bernabeu after Antonio Rudiger's header followed Mason Mount's finish earlier in Tuesday's second leg of their Champions League quarterfinal meeting.

Real Madrid players contested the corner that led to Rudiger's goal after the referee incorrectly ruled the ball had deflected off Luka Modric's foot and out of play.
