Former Manchester United captain Roy Keane claims Luis Nani should have no complaints following his controversial sending off during the Red Devils' Champions League defeat at the hands of Real Madrid.

Nani played a part in the opening goal of the evening as his cross was turned in by Real Madrid captain Sergio Ramos, as Manchester United seized control of the tie that had been delicately poised at 1-1 from the first leg at the Santiago Bernabeu.

The Portuguese winger was, however, soon red carded after catching Alvaro Arbeloa with a high boot, leaving Manchester United manager Sir Alex Ferguson apoplectic and allowing Real Madrid back into the encounter.

Luka Modric fired a leveller for the Spanish champions before former Old Trafford hero Cristiano Ronaldo slid in to divert the winner from Gonzalo Higuain's cross, but Nani's sending remained the major talking point after the match.

Ferguson was too 'distraught' in the aftermath to speak to the press, but Keane believes the referee made the correct decision to send Nani off, and says the 26-year-old made the mistake of giving the official from Turkey a reason to bring out the red card. 

"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.

"I don't think the referee made the decision because he waited a couple of minutes while one of the players was getting treatment and I think it was the assistant that made the call. Whatever people are getting upset about it, but I think he made the right call.

"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."
