Ferguson:
"We just clicked tonight.
"We are still there.
"The name of the game is to keep winning. That is the best recipe and best energy-enhancer of all time, winning. We can handle that.
"They (Middlesbrough) are still in the cup too. We will approach it the way we did today. We will use our squad in the right way.
"We will start utilising our pool, which we have been doing for the last three weeks.
"There was a good pitch - everything was in our favour but the goal on half-time brought Middlesbrough back.
"But we never gave in and we got our deserved equaliser."
Gareth Southgate:
"Everybody will have written us off - I think most people wrote us off before the game today, and we came very, very close to turning them over.
"When you are in the position we were in, you have the belief you are going to go on and win it.
"We had that belief all week that we could win the tie today, and that was the expectation once we went ahead with the way we have been playing.
"We played well in the second half and you think you are going to get there.
"We were obviously bitterly disappointed to concede, but we are still in there.
"We have got to remember they put their strongest side out today - that is a mark of the respect they have for us as a team.
"We have pushed them all the way again and we are still in there fighting."
On the penalty:
"I can see why he has given it because George has got his hands up.
"We don't like to complain about referees really but he's a yard away when it's flicked so I'm not quite sure what he can do to adjust his position."
George Boateng (about the penalty):
"I have had a look at it again. At the time, I felt it was very harsh.
"He did raise his hands, the only thing I feel is he was only a yard away from him when it was flicked and it is very difficult for anybody to adjust their body in that split-second of time.
"But there we go, we do not complain about referees' decisions here afterwards. He gave it honestly and we have to live with that."
