The City boss confessed experiencing "embarrassment" after an exchange with a camera operator in the wake of Manchester City's loss at Newcastle this past weekend.
At full time, an emotional Guardiola entered the St James’ Park pitch and had heated discussions with match official Sam Barrott and Newcastle’s Bruno Guimarães, and also touched the broadcast crew's equipment.
"I said sorry," Guardiola stated. "I feel embarrassed, ashamed, when I see it. I don’t like it. I apologised after one second to the cameraman. I am who I am. With a thousand matches under my belt I'm far from perfect, I make huge mistakes."
"What is for sure, I stand by my team and club, that’s for sure. Why I want to defend my team is no doubt – based on my career to win the Premier League we have to do 100 points, high nineties, otherwise we don’t win it."
City are third and are seven behind the Gunners following their fourth loss this campaign. "Losing four games out of 12 means we must do better," he conceded. "Mathematically, it’s possible to win everything."
When questioned about a potential quadruple was a realistic aim, he responded: "You are an experienced journalist, have you ever heard me discuss four trophies last winter when we won the quadruple? No."
On the subject of his talk with Guimarães, Guardiola said: "We have known Bruno for many years and every time after the game, even at the Etihad, we converse. We often meet and we get along well. I enjoy it. I’m an emotional guy, I love to talk and move my hands."
He wouldn't mind if an opposition manager addressed his squad right after the final whistle. "Not if it's respectful as I do, it’s not a problem," he said, mentioning the referee. "He was part of it for 95 minutes, 98 minutes, he was involved. My God, very much so."
City were unhappy that the officials did not award City a penalty on a Schär tackle against Foden, while they also questioned Bruno's positioning on Barnes' goal Newcastle’s 70th-minute winner. Subsequent images show he was level.
He will manage of his 100th Champions League game versus Leverkusen this week. "That's impressive, showing we compete we have been there," he commented.
City have 10 points after four games in the group, and Leverkusen hold five.
