On Thursday, a leading City supporters group labelled Guardiola's comments about stay away fans after the RB Leipzig game "disappointing and uncalled for".
"It's not factual, our attendances are generally excellent," said Kevin Parker, general secretary of City's official supporters' club.
"He [Guardiola] doesn't understand the difficulties that some people might have getting to a game on a Wednesday evening at 8pm."
However, Guardiola passionately argued that he would never criticise City fans for being unable to attend games.
"I am entirely grateful for the support that we had against Leipzig," added the 50-year-old, who celebrated his 300th game in charge with a stylish 6-3 win over the Bundesliga side in their Champions League opener.
"I always say if guys want to come we will be incredibly grateful because I know how difficult the game will be and I know we need our people.
"I never sit here and ask why people don't come. If you can't come then don't.
"If it's a problem for fans, I will step aside. From day one, I do my best. I like to play at the Etihad with my fans... my intentions are to be part of something, to do it together."
