Beckham believes that if England had beaten Brazil they would have gone on to win the tournament.
He said: "It was Brazil in the quarterfinals-Win that game and we'll win the World Cup. I know, back at home, people were starting to take it very seriously.
"In the past, high expectations put pressure on the team. In Japan 2002, though, our fans weren't thinking anything, me and the other players weren't already thinking ourselves.
"Argentina? Out. The holders, France? Out. Italy? Out. Portugal? Out. The Dutch? Not even there.Who was left in?
"Of the teams with a World Cup history, it came down to two: Germany, who we'd beaten 5-1 in Munich to get to the finals, and Brazil. We couldn't wait for Friday afternoon and Shizuoka."
Beckham also revealed how his new Real Madrid team-mate Ronaldo was laughing as England's players wilted in the heat.
He said: "Ronaldo was standing with the referee, talking about something - and then he started laughing and put his arm around the ref's shoulder.
"He looked like this was him and a few mates enjoying a Wednesday night kickabout down the local park, without a care in the world. How can you be doing that, 1-0 down at the World Cup?
"The look on the England players' faces said it all.
"We're knackered, we've nothing left. It was the story of our World Cup. We played our best football in the first half of games and then ran out of steam after half-time."
