The Portuguese has sparked controversy again after appearing to shove a young boy who was filming the Chelsea boss on his mobile phone.
The video shows the Chelsea Boss on a call while walking along a street in Knightsbridge, west London.
But as the Blues boss realises he is being filmed by the teenager, Otto Nahmmacher, he apparently pushes away the 14-year-old in anger, causing the footage to vibrate.
Nahmmacher’s father, Hans, told the Sun that Mourinho is “losing the plot”.
Hans, lifelong Chelsea supporter, said:
‘He saw him and thought, “That’s Mourinho, it’s my hero”. But this has put him off Mourinho, it’s woken him up to him definitely.
‘It’s really shaken him. Jose was a real hero for my son. We are both die-hard fans. I think it’s been 10 years since I took him to his first Chelsea match.
‘It’s a real shocker when one of your heroes does that.’
‘I can understand people getting up tight on the football field, that’s part of the game, however it’s quite different when it’s a young fan.
‘I couldn’t believe it when my son showed me the video on his phone.
‘I think it’s completely out of order that he goes for a kid and especially as it’s from behind. Is completely unacceptable.
‘They say never meet your idols and this is a real example of that.
‘My son was quite shaken up and disappointed. It’s no way to treat anyone, especially a kid who’s also a fan.’
The incident took place 24 hours after Chelsea’s win over Aston Villa at Stamford Bridge.
