Pep Guardiola has apologised for his confrontation with a cameraman after Manchester City's weekend loss to Newcastle, saying he feels "ashamed".
The City manager had grabbed the cameraman's headset and appeared to say something directly into his ear after the final whistle of a 2-1 loss at St James' Park.
Guardiola had been involved in heated discussions with Newcastle captain Bruno Guimaraes and match officials.
"I apologise. I feel embarrassed, ashamed when I see it. I don't like it," Guardiola said at a press conference on Monday (local time) ahead of City's home game on Tuesday against Bayer Leverkusen in the Champions League.
He added that he had apologised to the cameraman "after one second".
"I am who I am - even (after) 1000 games, I'm not perfect a person,'' Guardiola said.
"I made a huge mistake. What is for sure, I defend my team and my club, that's for sure."
