Fabio Capello refused to blame his players for England's woeful exit from the FIFA World Cup™ at the hands of Germany.
Assistant referee Mauricio Espinosa failed to spot it, though, and instead of drawing level at 2-2, England capitulated in the second half to lose 4-1, their worst ever World Cup defeat.
"It was one of the most important things in the game," Capello told BBC1.
"We scored two goals and at that moment, I saw Germany suffer a lot.
"The [disallowed] goal was very important. We could have played a different style.
"We played I think well at 2-1, but after the third goal it was a little bit disappointing.
"Look, we probably arrived a little bit tired at the end of the season.
"But after the game that they played against Slovenia, we suffered from Germany's speed today.
"But I say again, I am sure that a big mistake from the referee stopped us from going forward."
Capello is now to seek urgent talks with Club England chairman Sir David Richards about his future.
His position is bound to come under intense scrutiny only five weeks after having a clause removed from his £6million-a-year deal that would allow either party to terminate the contract after the World Cup.
"I want to speak with the chairman and then decide my future," said Capello.
"I need to know whether the FA have confidence in me or not."
Senior sources within the Club England camp who will determine whether the Italian stays or not have indicated that their stance on Capello - that he is the right man to take the Three Lions forward - has not shifted as a result of one single, albeit controversial result.
