David Beckham has revealed that he couldn't watch Manchester United for two years after he left Old Trafford in 2003 because he was too "gutted".
The former England captain left the Red Devils to join Spanish giants Real Madrid, but admits it was a painful experience.
"I realised that my dream of continuing to play for Manchester United was over and I needed to pick another team," Beckham told BT Sport's Jake Humphrey at his new photo book launch. "I was lucky that Real Madrid wanted me, but in all honesty I couldn't watch Manchester United for two years. I was that gutted.
"It was that difficult to leave and that difficult to come to terms that I wasn't there anymore."
Beckham, who was one of Manchester United's famed Class of '92 members, won six Premier League titles, two FA Cups and one Champions League during his 10-year professional career at Old Trafford.
His former manager, Sir Alex Ferguson, explains in his recently-released autobiography that he sold Beckham after the winger started to get too big for his boots. Ferguson also claims that Beckham was the only player he managed who wanted to become a celebrity.
However, the former Manchester United, Real Madrid, LA Galaxy, AC Milan and PSG midfielder refused to criticise his ex-manager's uncomplimentary comments.
After leaving Old Trafford, Beckham went on to win one La Liga title, two MLS Cups and, finally, a Ligue 1 trophy with PSG before retiring at the end of last season.
