"I think we gave the goals away very cheaply and at that level you can't do that," Ferguson told Sky Sports.
"They were better prepared physically, they've been resting players and that can make a difference.
"They were certainly sharper and quicker to the ball and pressed really well and I think they've been good winners.
"We were on the back foot all the time and found it difficult.
"For 15 minutes after half-time it looked as if we were getting some momentum and had a half chance but we needed that goal to turn the game round.
"In fairness we didn't really look as if we were going to score."
Ferguson on the weekend
"You have to put disappointment behind you, we've handled it in the past and I'm sure they will handle it on Saturday,"
"They can win the title, we have to make sure they recover in the proper way. We are not helped by the 12:45pm kick-off but we will be there."
"Watching your team playing as we did in the first half is the dream of every coach," said Ancelotti. "In the first 45 minutes we played the perfect football. We built our victory from a great start."
"It will be a very fascinating match against Liverpool. They are a more physical side compared to Manchester United. Champions League football is peculiar but I think Milan are the best side in Europe in playing this kind of games.
"We rarely play a bad game at this level. Most of all, however, I'm happy because we are at top physical condition in the right moment of the season. We did a great job during the Christmas break and now we can see the results.
"We are very happy to be playing in the final and equally happy to face Liverpool,"
"What happened two years ago has no weight on the upcoming final. We want to win it."
"My team-mates made me a great gift because I wanted so much to play that final against Liverpool," he said.
"The memory of Istanbul still hurts. We are in great physical condition in the right moment of the season. It will be a very tough game but we fear nobody at this stage."
