Man Utd v Real Madrid facts
- Real Madrid had only previously advanced once in the Champions League after recording a home draw in the first leg, but that was also against Manchester United in 1999-2000
- Real Madrid are now the only team to win away to Manchester United twice in the Champions League
- Cristiano Ronaldo's winning goal was his eighth goal in eight games in the competition this season
Following a 1-1 draw in Spain,
United had edged a tight second-leg opening in which captain Nemanja Vidic struck the post with a powerful header.
They finally took the lead - on the night and on aggregate - at the start of the second half, when Sergio Ramos deflected Nani's cross into his own net.
The match then turned in Real's favour just before the hour mark when referee Cuneyt Cakir dismissed the Portuguese for a high boot that made contact with Alvaro Arbeloa's rib-cage.
Mourinho's side took advantage of the decision in clinical fashion.
Former Tottenham player Modric
curled in a sublime equaliser after he came off the substitute's bench, and Ronaldo scored from close range after a stylish move.
"My feeling is that Manchester United were playing very well, were very compact and aggressive in a good way," Mourinho added. "I doubt that 11 v 11 we win the match.
"I know Manchester United are giants, not just physically but mentally. I know they have a manager who can motivate then, but I was waiting for us to play in a different way."
Before kick-off, Ronaldo was given a warm reception by supporters at the club where he had played a pivotal role in the
winning of the Champions League in 2008,
as well as three Premier League titles, in a six-year spell in England.
The attacker - who moved to Real for a record £80m fee in 2009 - admitted he had been overwhelmed by the reaction.
"It was unbelievable," he said. "It was an emotional moment for me, for both games, but especially tonight.
"I do not have words to explain how I feel. The supporters made me feel shy. I did not play how I play all the time."
When asked to comment on rumours of a potential return to Old Trafford,
he replied: "The future I never know, but the supporters here and the club are massive.
"At this moment I am very happy in Madrid and I want to be there."
