Beckham inherited the number from Eric Cantona.
He told the Daily Mal: "I looked up to Bryan Robson; he was the player I wanted to become. He wore number seven for England, number seven for Manchester United, he captained England and he was the person that I really looked up to.
"I also looked up to Sir Bobby Charlton because he was my dad’s hero and when you think about heroes, my dad was one of mine."
