Ferguson was speaking following his side's first pre-season run-out, a 2-0 win over his former side Aberdeen in a testimonial for the Dons' European Cup Winners' Cup-winning side of 25 years ago.
The Scot enjoyed the chance to remember his first triumph on the European stage, but made sure the occasion did not overshadow his focus on the team's performance at Pittodrie.
"It was a good day for me, it was emotional driving up to the stadium and seeing people you haven't seen for years," said Ferguson after a first-half Michael Carrick penalty and a Wayne Rooney header gave United a 2-0 win.
"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.
"Wayne had a couple of chances in the first half and made some nice runs round the shoulders of defenders which could have got us a couple of goals.
"He made the goal and scored the header so he will be happy."
Ferguson refused to answer questions on Fifa president Sepp Blatter's recent comments about Cristiano Ronaldo's future at the club.
