Willie Miller greeted Sir Alex Ferguson during the pre-season friendly
A first-half Michael Carrick penalty and a Wayne Rooney header gave Manchester United a comfortable win over Aberdeen on Saturday.
Sir Alex Ferguson - who managed Aberdeen from 1978 to 1986 - had returned to the city with his Champions League winners.
The game marked the 25th anniversary of the Dons winning the European Cup Winners' Cup in 1983.
Sir Alex said it had been an "emotional" trip to Pittodrie.
Tickets for the glamour game were quickly sold out.
It was the highlight of a series of testimonial events to honour the European victory.
Sir Alex led Aberdeen to three Scottish championships, four Scottish Cups, one League Cup, the Cup Winners' Cup and the European Super Cup.
It was the Dons' first pre-season friendly, but manager Jimmy Calderwood was delighted to have such illustrious visitors.
Sir Alex was pleased with the run-out and especially the contribution of Rooney.
He said: "It was a good day for me, it was emotional driving up to the stadium and seeing people you haven't seen for years.
"It was our first game and it was quite an open match and easy for both teams.
"They had a couple of chances and we had to defend well at times so it was good."
