Beckham was near the height of his powers when he was sold by United to Real Madrid in 2003 but Ferguson feels the matter has long since been consigned to history.
The pair will be reunited this month when the Red Devils take on the midfielder's current club, AC Milan, in the Champions League. Ferguson is now more concerned about how his players will handle the inevitable attention that will accompany Beckham during the last-16 tie than wondering about what might have been.
When asked about the player's £25million move from Old Trafford, Ferguson told the club's official magazine `Inside United': "No regrets. We move on."
He added: "The only difference with David's return to Manchester United compared with other players is that there will be a big media circus surrounding him when Milan arrive.
"He's such a high-profile celebrity - not just a high-profile footballer - and we haven't really seen anybody else return to the club in that situation. Our job is to concentrate on the football match and let the David Beckham media circus carry on - we know we're not going to stop it anyway."
