He also praised his players for learning lessons from their previous Celtic Park visit after knocking the holders out of the Scottish Cup.
The Dons came from behind to win 2-1 in Glasgow and reach the quarter-finals of the cup to keep the dream of a cup double alive.
And the Dons boss said: I’m delighted for every one of our supporters that's come here.
"We've had a few sore ones over the years and it's been a long time since we've managed to get a victory here.
"Today was a proper team performance. It wasn't about individuals. The platform's all about denying them space, never being stretched.
"People will talk about maybe Celtic's failings and maybe they fell short at times and they've got a bit more quality to show than that but I do feel that we played a part in that.
"It's a great result."
