|MAN UTD 1-2 REAL MADRID (AGG 2-3)
The Portuguese was dismissed for a high challenge on Alvaro Arbeloa as both players contested an aerial ball.
The Manchester United midfielder seemingly had his eyes on the ball but the Turkish official deemed it dangerous play and reduced the hosts to ten men.
Real Madrid gained the impetus following the dismissal and soon turned the tie around with two goals in quick succession.
First Luka Modric evaded two challenges before firing in a rasping shot past the helpless David de Gea before Gonzalo Higuain found Cristiano Ronaldo at the back post with a low cross for the former United man to score against his old side.
