AC Milan loanee David Beckham has revealed that he wanted to remain at Manchester United when he was sold to Real Madrid in 2003.

As the England international prepares to take on his old side in the Round of 16 second leg clash at Old Trafford, he has spoken of how big a challenge it will be to come up against United at home and said he would have loved to have stayed a Red Devil for his entire career.

"It's a massive challenge," said Beckham. "To win at Old Trafford is a really big ask, but I love the prospect of big challenges.

"If I'm given the chance to play and prove what I can still do then that would be a great test for me and the team.

"I wanted to stay at United for my whole career, but sometimes things aren't meant to be.

"I've been to three clubs since I left United, but it would have been great to stay there like Ryan Giggs."
