The goalkeeper has refused to deny the authenticity of the strike, which would have afforded England a rare opportunity to stage a magnificient comeback.
Neuer said: "I saw the ball, I quickly picked it up and I quickly restarted.
"If I had looked right or left, perhaps it would have struck the referee's attention. Maybe, he might have considered awarding the goal.
"Clearly it was valid, I don't have any doubt about it, I've seen the replays also."
The Germans beat their English counterparts (4-1), to aid their onward progress into the quarter-finals of the ongoing Fifa 2010 World Cup tournament in South Africa.
