Beckham faces his former club for the first time tonight in AC Milan's colours.
"David left seven years ago," Ferguson stated. "You move on in life. That is what happens.
"This is a different team and different players.
"It is the same experience as the likes of Alessandro Nesta, Filippo Inzaghi and Clarence Seedorf. They all have that experience that Milan bring and I hope he is not celebrating at the end."
