Sergio Ramos didn't just take Mohamed Salah out of the game by dragging him down to the floor and injuring his shoulder, but he also may have had a big impact on Loris Karius' errors.
In the 49th minute Ramos was in the box and he elbowed Karius in the head, with the goalkepeer falling down. Howeve r none of the referees noticed.
Then shortly afterwards Karius gave the ball straight to Karim Benzema for Madrid's opening goal. Later he spooned Bale's shot from long range into his own net.
