An England supporter sparked a major security scare by storming into the team's dressing room to rant at Fabio Capello and his players after their World Cup goalless draw with Algeria.
The intruder, wearing an England shirt, burst in just a few minutes before Prince William and Prince Harry were due to meet the players, and had to be talked out of the room by David Beckham.

Moments earlier, Wayne Rooney had snapped at fans as he marched from the pitch and snar led a foul -mouthed message down the lens of a television camera.
'Nice to see your own fans booing you,' a furious Rooney could be heard to say. 'That's what loyal support is - for ****'s sake.'
It was a chaotic and fractious night all round for Capello and his team as they stumbled to a draw against the unfancied North Africans, who are at their first World Cup for 24 years and ranked 30 in the world.
'The fans can decide to do what they prefer,' said the manager, who criticised his players and claimed they were stifled by fear. 'I didn't hear the boos because of the vuvuzelas.'
Point and shout: But Fabio Capello was unable to galvanise his side
The FA will lodge a formal complaint to FIFA today about the security lapse at the Green Point Stadium.
England were disappointing against the USA in Rustenburg last Saturday and worse still last night against the Algerians.
A win against Slovenia on Wednesday will still be enough to qualify for the last 16 - they could even top the group - but they will be without Jamie Carragher, who collected his second booking in one-and-a-half games and will miss the game in Port Elizabeth.
Prospects would have been even worse had the USA not fought back from two down to draw against Slovenia earlier yesterday, as Ashley Cole acknowledged later.
'We were lucky the USA got a draw,' he said.
Former England boss Graham Taylor said on BBC Radio that he feared Capello's team may not even get out of the group and raised doubts about the harmony in the camp.

'I do now believe there's a real danger of England going out,' said Taylor. 'There's something not right behind the scenes. I don't know what it is. I have an idea; I don't believe the proper preparatory work is being done. Look at the body language: something's wrong.'
Goalkeeper David James replaced Rob Green, axed after his dreadful mistake against the USA, and he offered a prickly response when asked about Capello's theory that the team were playing with fear.

Message: An England fan's memo to Fabio Capello
'I don't know why he said that,' said James. 'It was more frustration than fear. Algeria just didn't want to lose. We can recover, without a doubt.'
Rooney's form will worry Capello, but John Terry said: 'There is no pressure on Wayne. He does what he does and is one of the best in the world for it. Obviously Wayne is frustrated. Everybody in the dressing-room is feeling the same as Wayne. I would ask the fans to stay behind us. We need them fully behind us. It is in our hands.'
Wayne Rooney was unhappy with England fans booing the players after their 0-0 draw with Algeria last night.
The Manchester United striker trudged off following an ineffective performance.
He told the ITV cameras: "It's nice to see your home fans booing you."
The result means England need to beat Slovenia next Wednesday to ensure they qualify for the last 16.
Midfielder Gareth Barry understood the fans' frustration.
He said: "It is a long way to come out here, they want what's best for us and we do too. We want to qualify and they want to extend their stay out here and see us go as far as possible.
"On Wednesday night that is just the small push for us to try and do it for the fans."
Captain Steven Gerrard made no excuses for the display in which the team were sloppy throughout and rarely threatened the Algeria goal.
The Liverpool skipper told ITV1: "We're not happy with the performance, we need more.
"We want to stay in this tournament until the final stages.
"We were not good enough to make the breakthrough in the final third.
"We've not got any excuses, we know what we have to do. We have to win the final game which adds to the pressure but at this level you have to handle that pressure.
"We were not aggressive enough and didn't have the cutting edge in the final third.
"Give them (Algeria) credit but we have to look at ourselves."
