The England midfield ace is tonight set to make his first appearance at Old Trafford since leaving Manchester United for Real Madrid in 2003 after a very public falling out with Ferguson.
But while Beckham admits he had no desire to leave the club he supported as a boy he also insists that he will forever be grateful for the role Ferguson played in shaping his career, which has seen him play for United, Madrid and now AC Milan, as well as amassing over 100 caps for England.
'I wanted to stay for my whole career, but sometimes things aren't meant to be,' Beckham told Match the Day magazine, on sale now.

'I've been to three great clubs since I left United, but it would've been great to stay there like Ryan Giggs has. Being at one club for so long is a real achievement.'
On his relationship with Ferguson, Beckham added: 'It will be good to see him again. He's a scary man, but in a really good way.
'He's played such an important role in my life, and during my time at United he was like a father figure to me and I will always be grateful for that.'
