The Red Devils reversed the scoreline of their last visit to Newcastle with a 3-0 win, and the manager was particularly impressed with Wayne Rooney's efforts in midfield
Two goals from corners in the first half took the Red Devils out of sight, and Tom Cleverley’s cross-cum-shot rounded off an excellent display from the visitors.
The Red Devils looked keen to bounce back from their defeat at home to Tottenham last time out, and Ferguson was delighted with the way his side kept their concentration.
"It’s a great result against a powerful Newcastle team," he told Sky Sports. "We came here to perform and make sure we keep control of the game and I think we did that most of the time.
"Last time we were bullied off the pitch and second to every ball last year but tonight it didn’t happen.
"The second half against Tottenham we were terrific; an absolutely brilliant performance. But the first half spoiled the whole day, but today the whole game we were really on top our game in terms of concentration, determination, all the things you want to see.
"Concentration is important at this level and we concentrated on the way we played first 20 minutes. It’s strange as we played such good football and created a lot of openings but scored from two set-pieces. That’s unusual for us but we’ll take it anyway."
The Scot also praised Wayne Rooney’s contribution to the win, with the England international slotting into a slightly deeper role for the visitors after coming back from injury.
"He’s getting fitter all the time," added the 70-year-old. "He needs the games obviously. With about 20 minutes to go I could see signs he was starting to tire a little but he’s put so much work into it. Some of his football was terrific today."
After an international break the Red Devils host Stoke, and Ferguson accepts the importance of getting a result to keep in touch with Premier League leaders Chelsea.
"You don’t want to fall too far behind," he said. "If we hadn’t won today we’d have been seven points behind Chelsea. We’re in the frame, we’re still there and every game is important now because you want to stay up there and hopefully we can do that."
