Former footballer David Beckham is proud to have a wife as caring as Victoria Beckham, who `really understood` him when he injured his ankle and couldn't play in the 2010 World Cup tournament.

He has spoken of his appreciation for Victoria in previously unaired scenes from "David Beckham Into the Unknown", a documentary about his life, reports femalefirst.co.uk.

In the video, he is heard saying: `The doctor came over to me and gave me the phone. Victoria was on the phone and she said 'What happened?' And I said to her 'It's done'. And she said, 'What do you mean it's done?'

`And I remember, I'll never forget she just burst out unconditionally with emotion and crying, when someone just kind of can't get their breath. She literally handed the phone to one of the boys and the boys were upset.

`That was one of the points when I knew I had a wife that really understood me and really understood why I was doing it. She knew how much it meant to me, she knew how much playing in a fourth World Cup meant to me. That was a tough time for me."

`David Beckham Into the Unknown` is out on DVD.
