Manchester City manager Pep Guardiola has admitted he was "embarrassed and ashamed" of his conduct after confronting a cameraman in the aftermath of the club's costly 2-1 defeat at Newcastle on Saturday.
The City manager reacted angrily when a camera was pushed close to him following the final whistle, at a moment when he was speaking to Newcastle's Bruno Guimares and the match officials.
Guardiola had been incensed by the decision to allow Newcastle's decisive 70th-minute goal, believing that goalkeeper Gianluigi Donnarumma had been fouled in the build-up.
