New footage revealed by The Independent has shown Jose Mourinho apparently losing his temper with another young fan as he tried to take a photo.
Sonnie Burgess was with friend Otto Nahmmacher when they spotted the Chelsea manager walking along a street in Knightsbridge on Sunday.
The 16-year-old described their encounter in an exclusive interview with The Independent, saying: “We were cycling home when we bumped into Mourinho and asked him for a picture and I was recording it.
“He was giving me dirty looks and he was being quite anti-social and aggressive.”
As the manager ignored the teenager and carried on walking, talking on his phone, Sonnie asked for a photo again and was refused.
Otto alleged that he was "shoved" moments later as he attempted to capture a selfie with the 52-year-old football manager.
Sonnie claimed Mourinho then walked away without making any move to apologise to the teenagers, adding: “We were genuinely scared.”
He said he was left shocked and upset by his hero’s reaction.
“I love Chelsea and I love Jose Mourinho and I lost so much respect for him,” Sonnie added. “He was my hero and now it’s crushed everything.”
Sonnie, who lives in Battersea and is in his last year at a secondary school in Wandsworth, said the incident started at around 3.15pm and was over less than 10 minutes later.
“I’m a season ticket holder but I’m thinking of cancelling it,” he added. “It’s completely changed me.”
Chelsea had enjoyed a comfortable 2-0 home win over Aston Villa the previous day and drew in a goalless Champion’s League draw with Dynamo Kiev on Tuesday.

After the police questioned him over whether his dog had a pet passport.
3/15 The Devil in disguise
'Some clubs are treated as devils, some are treated as angels. I don't think we are so ugly that we should be seen as the devil and I don't think Arsene Wenger and David Dein (pictured) are so beautiful that they should be viewed as angels'
4/15 Arsene Wenger's appaent 'voyeur sickness'
'Wenger has a real problem with us and I think he is what you call in England a voyeur. He is someone who likes to watch other people. There are some guys who, when they are at home, have this big telescope to look into the homes of other people and see what is happening. Wenger must be one of them - and it is a sickness'
5/15 Look who's talking now
'I don't regret it. The only thing I have to understand is I'm in England, so maybe even when I think I am not wrong, I have to adapt to your country and I have to respect that. I have a lot of respect for Liverpool fans and what I did, the sign of silence - 'shut your mouth' - was not for them, it was for the English press'

7/15 On THAT Luis Garcia goal
'I felt the power of Anfield, it was magnificent. I felt it didn't interfere with my players but maybe it interfered with other people and maybe it interfered with the result. You should ask the linesman why he gave a goal. Because, to give a goal, the ball must be 100% in and he must be 100% sure that the ball is in'
Mourinho questions the validity of Liverpool forward Luis Garcia's goal which puts Chelsea out of the Champions League semi-finals in May 2005.

'No eggs, no omelette. And it depends on the quality of the eggs. In the supermarket, you have eggs class one, class two, class three. Some are more expensive than others and some give you better omelettes. So when the class one eggs are in Waitrose and you cannot go there, you have a problem'
A parting shot at Abramovich, coming ahead of his final match in charge, for the Russian's failure to buy quality players to help his injury-hit squad.

Mourinho has his chefs' hat on again to describe the squad he has inherited on his return to Stamford Bridge

15/15 Specialist in failure
'He's a specialist in failure'
Mourinho gets himself labelled silly by Arsene Wenger and a bully by Bob Wilson after saying this about his Arsenal counterpart. It was in response to Wenger suggesting his title rivals were playing down their chances of winning the league due to a fear of failure.
The result compounded a difficult start to the season for the Blues and their manager, who was fined £50,000 by the Football Association for criticising a referee and publicly admonished Chelsea medic Eva Carneiro, who subsequently left the club.
Chelsea did not respond to The Independent's request for a comment.
