Ian McCall's formation was much altered from the side that lost to Motherwell only two weeks ago with Paul Gallacher in goal and David McCracken and Mark Wilson back in the side. Jim Paterson also returned after recovering from injury and Billy Dodds was restored to the stating line-up.
The Tangerines began strongly and were denied a penalty very early in the game when the ball appeared to be played by the arm of McGuire, but the referee waived the claims away. However, with barely ten minutes gone, United took the lead and Mark Wilson was the provider. After a mazy run, he fed the ball to McLaren wide on the left and the winger went for goal and scored with the help of a wicked deflection off Anderson.
Zdrilic missed a great chance to level when he fired over the top and for United Wilson released a well-executed free-kick to which Innes got a touch but the ball spun up and hit the bar.
The Dons' best chance to get back into the match came in the second half as Gallacher spilled a Tosh effort into the path of Booth but McCracken was first to react and cleared the danger.
Jim McIntyre was unlucky not to put the match beyond the home side late in the second period. He gathered a slack pass back and was only thwarted by quick thinking by Preece who closed the striker down.
Aberdeen did have the ball in the net in injury time but the attempt was quite correctly ruled offside.
Overall United were the better side on the day and well worthy of the three points which see the Tannadice side leapfrog their New Firm rivals into tenth spot in the league.
