The Scot changed his entire team for the away game but was pleased with the result and particularly his experienced strike partnership, who both chipped in with goals
It was an entirely different side from the team that lost 6-1 to Manchester City, and Ferguson was happy with the way his team had performed, especially the strike partnership of Michael Owen and Dimitar Berbatov.
"The players always give me nudges [to play]," he told Sky Sports. "It's difficult picking a team when you've got so many good players, we've got a fantastic squad, that's why I'm bound to play these players tonight, they need games.
"They've not had too many first-team games to be honest because the consistency of the team has been very good, we've not had to make any changes.
"But with Michael Owen, every time he plays, he scores; it's a fantastic record he's got, he's a fantastic professional.
"Dimitar Berbatov has had a fantastic game tonight, scored a tremendous goal from great football. So they've all done well, [Antonio] Valencia, Tom Cleverley's back as well which is really good because the boy is an outstanding footballer."
The United boss was also very complimentary of Dean Holdsworth's Aldershot team, and was happy with the way his side dealt with the threat of an upset.
"I think Aldershot have fought really hard and they take a lot of credit, they never stopped running, they never stopped pressing the ball, they put in a good shift.
"We obviously showed our quality at times and could have maybe scored a few towards the end of the match when they tired.
"[In] the cup ties, the most important thing is to win the game and we're into the next round now.
"I think professionalism and discipline, they maintained that, they have kept consistency in passing the ball and that is a good habit to have in these types of matches."
Ferguson was also pleased that his players enjoyed the game, following such a poor result two days before.
"I think in the end we're looking for [the players' minds to be focussed]; I think that we had a difficult day on Sunday because we tried to prove the history book.
"But if we'd have kept our discipline, just played out the game with 10 men, but the nature of Manchester United is to win the game with 10 men, 11 men, seven men, and it's very difficult to change that.
"They enjoyed it tonight, the players enjoyed it."
