Hughes:
"We are in a situation now where there are only so many Premier League referees, and possibly they enjoy the celebrity status - that's dangerous," said Hughes.
"Tonight, Mr Poll thought 61,000 people had come to see him.
"Referees have to remember fans come to watch two teams play, not the performance of the referee.
"I am particularly disappointed with the penalty decisions. We had a very similar, if not stronger claim early in the second half which wasn't given.
'We get pulled up and yellow-carded for things, but in other situations Manchester United players didn't'
"Okay, it was a great save by Brad Friedel and that didn't cost us, but there were a number of other decisions right through the game that led to frustration on our part.
"I feel there needed to be a balance in the amount of decisions we had and that Manchester United had.
"We get pulled up and yellow-carded for things, but in other situations Manchester United players didn't.
"The second tackle on Robbie, coming so close to the first after Steven, I thought should have been a yellow card.
"You'll have to ask Mr Poll why he didn't yellow-card Van Nistelrooy in that instance.
"But it's not something we want to harp on about as the game has gone and we cannot do anything to change what happened."
On Saha's goal:
It was a great effort from our guys. I'm not sure Louis Saha meant what he did for their second goal and at the end United went to five at the back. I've not seen that many times at Old Trafford and it shows the effort we put in. But I'm desperately disappointed for the players because it's been a great effort."
Fergie:
"Freidel was fantastic.
"Three of his saves were world class. He kept them in the game, no question about that.
"On the last four occasions we have played them he must have made 40 saves against us."
"Blackburn did not give up and why should they because they are a mirror of their manager.
"They make the referee work and they make you work.
"They are just a difficult side to play against because they have some very competitive, aggressive players, but they are also a good side."
Saha:
"We are in Cardiff now, so it is good. It was a great performance.
"We expect a big game against Wigan. It is going to be tough but we are confident we can win it.
"Both legs were tough games. Blackburn had a real go but we managed to come through.
"Getting to any final is great. We are in this competition to win it and hopefully we can do it."
Rooney:
"Blackburn had a real go at us, but we knew it would be a tough game and we managed to hold on. We are delighted to have got through — reaching any cup final is a great feeling."
Paul Jewell was at OT:
They will be strong favourites.
"To be in a final with arguably the biggest club in the world will be a great day out - but we are not just going for the day out."
