Trailing 2-1 from the first leg of their last-16 tie, Portuguese star Ronaldo hit two early openers before settling the tie with three minutes remaining to calm his team's nerves after Sergio Ramos had been sent off with 17 minutes to go.

Sami Khedira added the fourth in the final minute and Jose Mourinho's men will now meet Valencia in the next round before a potential semi-final tie with eternal rivals Barcelona who knocked Madrid out last season at the quarter-final stage.
