Here is the reaction of the players and managers of yesterday's match:

Barcelona
Rijkaard
On The Penalty Miss: "The penalty miss was a decisive moment for us,"
"It was a bit of a wake-up call and after that we played well."
On The Match: "In pure football terms it was not our best performance, but the team transmitted something special to the crowd and it was a great atmosphere,"
"It was a very tactical game, Manchester played well on the counter-attack but we did not give them any chances and they know we are capable of scoring at Old Trafford.
"It will not be easy, we are up against a very good team but if we concentrate and remain positive, we know we can do it. A goalless draw is not the best result and we have to score over there, but it is not going to be easy for them. We will have our chances."
Xavi
On The Match: "The only thing missing was the goal and that leaves a bitter taste in the mouth. We dominated the 90 minutes. We are happy with the image we gave, but not the result,"
"This team is capable of going to any ground and winning, so I have no doubt we can make the final."
Manchester United
Ferguson
On The Match: "We sealed off the areas where teams don't normally do well against Barcelona.
"They didn't make a lot of chances. Going to Old Trafford at 0-0 we have a marvellous chance."
"They had a lot of play around the box but our concentration was very good.
"On the negative side we should have done better with possession. We had opportunities to counter-attack but gave the ball away too easily.
"The way they play they always have an extra man in midfield so possession is always going to be in their favour.
"You have to show patience and quality and Barcelona have that, but we had the answers.
"At Old Trafford we have to impose ourselves more and I think we will."
On Ronaldo's Penalty Miss and Penalty Claim: "Maybe it came too early. It was the first minute of the match and he leaned back a bit.
"He's disappointed but nevertheless he was magnificent."
"If you get one penalty in the Nou Camp you are doing well, to ask for two I'm not surprised it wasn't given."
On Paul Scholes: "His reading of the play outside the box was terrific," said Ferguson. "His interceptions were marvellous and he never gave the ball away."
Ronaldo
On The Game: "Well it was a tough game," Ronaldo told Sky Sports. "They keep the ball a lot I think we defended well, we play well and you know 0-0 away is a good result. I didn't change my style [for the penalty]. “I scored a few penalties in that side but today I didn't score - no problem."But now I will score in Manchester."
On The Penalty Claim: "I think he touched me. But the referee didn't give a penalty. I don't know why, I don't understand."
On The Second Leg: "I've scored a few penalties in that side but today I didn't score - no
