Ferguson:
"We're all delighted. I think it's appropriate with our history of winning the FA Cup more than any other club.
"We're all pleased at that.
"I've never seen the place, but they tell me it's spectacular. It's always been a special place the times we've been there and we've really enjoyed it
"It was a fantastic performance; it was as good as Tuesday in terms of the endurance of the team, the courage, accepting the disappointment with Ferdinand being injured when we had to change the team.
"It was absolutely magnificent, I was so proud.
"Hopefully it's not too serious. He'll [Ferdinand] have a scan in the morning and we'll get the results in the afternoon.
"It was his [Ronaldo's] 21st goal today and he could go on to score 25, the form he is in.
"Wayne Rooney had his best game of the season today, he was absolutely fantastic. And Alan Smith has brought a breath of fresh life to the team. He is doing fantastically for us."
More:
"Smith has breathed fresh life into the side. He's been incredible. I've had to organise the team to suit the talents.
"Ryan is definitely suited to playing the role he played. Wayne has no problem with that. We know his best position is through the middle but he scored two good goals today because he was constantly running inside people.
"Watford ask questions of you. They are honest, aggressive, brave players.
"They ask the question 'Are you going to stick your head in, because I am?' We passed that test and I was pleased with that.
"It was a blow when Ferdinand went off because we feared the worse at that stage. We are down to the bare bones defensively at the moment but we had the courage of Heinze and Brown.
"It's been a great tournament for me. That dressing room tonight, the atmosphere is special. It's fantastic. I've been telling Heinze and Evra and the others all about it and when they go they'll realise why everyone talks about Wembley.
"We've had to endure two replays and some scary moments this season. But we've played all Premiership opposition and not had any easy ties. We can take credit for that."
Rooney:
It was a big game today and Watford made it tough for us. We were looking to have a quick start and we managed that with the early goal. I scored a few goals playing from out wide so I'm sure that's where I'll probably play in the next game.
"They're a physical team and we knew at some point in the game we'd have to defend. I think up until 1-1 and just after half-time we had to battle and we did that well.
"Watford put us under pressure with some long balls and long throw-ins, so we were delighted to get the second goal and go into half-time 2-1 up.My second goal killed the game off. Alan Smith played a great ball into me and I couldn't miss from there.
"That's what you play for, to be in cup finals and to win.
"We're delighted we're into one cup final. Hopefully we can go far in the other competitions. We're scoring freely at the minute and we're looking to continue that."
Giggs:
"With the momentum we are building this team are capable of winning the treble. We need to carry on winning and that will build the confidence even more.
"The history books show they won it. This team has the ability but we still have to go out and win the trophies.
"It's a hell of a month coming up. The games are coming thick and fast.
"But we can put the FA Cup to bed until the Final and concentrate on the Premiership and Champions League.
"The defeat against Arsenal still haunts me," he said. "It was hard to take. To dominate the game and lose was dreadful.
"It's brilliant to think we are going to the new Wembley. I remember going to the old one as a young boy.
"Like any other kid I dreamed of playing in an FA Cup Final at Wembley and now that dream is going to become reality for me.
"I'm feeling good, doing well and scoring a few goals which is pleasing."
Ferdinand:
"I came off as a precaution and won't know until tomorrow how serious it is. But I'm confident it won't be too bad.
"I don't know about Tuesday (against Sheffield United) but think I should be all right for Saturday.
"It was the semi-final of the FA Cup, so I was disappointed to come off.
"I will speak to the physios about the injury, and I will obviously know more next week, but hopefully it is not too bad."
About the match:
"Once we knew the final was going to be played at Wembley, we wanted to get there even more.
"It has a great history. To be the first to play there will be phenomenal. Hopefully, we can go there and win.
"All that was important today was winning. The performance was secondary.
"We were disappointed to concede a goal but the response we are getting at the moment to conceding goals is more important than anything."
Watford manager Aidy Boothroyd:
"I asked for them to come off the pitch letting them know Manchester United had been in a game and we did that.
"We had them rattled at 2-1 but the way they play you are at your most vulnerable when you have got the ball.
"I am disappointed to go out but they were too strong. They can counter attack very quickly and have some wonderful players.
"But it was not as one-sided as the scoreline suggests. We had a game plan to frustrate and upset them and that proved to be the case."
