Former Manchester United captain Roy Keane believes that referee Cuneyt Cakir "made the right call" by sending off Nani during his side's clash with Real Madrid.

United were dumped out of the Champions League after losing 2-1 on Tuesday night at Old Trafford, and 3-2 on aggregate in a match that saw the Portugal international controversially sent off.

While many have criticised the decision of the referee, Keane has no sympathy for the winger.

"The referee has made the right call," Keane told ITV Sport. "It's dangerous play, it's a red card. He knows there are other footballers on the pitch and to be fair to the referee, he took a few minutes, spoke to his assistant and decided it was a red card.

"Any time I got sent off in my career, I always thought did I give the referee a chance to send me off? If the answer is yes, then it is out of your hands. Everyone is upset about it and United are slightly unlucky to go out, but it's dangerous play. Whether he meant it or not is irrelevant. It was dangerous play, red card.

"Whether the referee was brave or not, it was the right decision. Let's not forget that Nani is quick to go down, he is not always the bravest boy."

A Sergio Ramos own goal put the Red Devils in front on the night, but goals from Luka Modric and Cristiano Ronaldo gave the La Liga champions the win.
