Manchester United manager Jose Mourinho has questioned why some global teams are playing friendlies as well as competitive matches at this stage of the season.
And Guardiola told a news conference: "After the first half when we scored a goal, we forgot a little bit how to play".
"I'm not here to judge what they have to do and what is going to happen".
"In my experience in Spain, my experience in Germany and now here, you can not imagine how good the young English players are", he said ahead of City's trip to Arsenal on Sunday, before evoking England's once feted "Golden Generation".
City did not did not take their chances against Liverpool and they did not control the game, but Guardiola, given the reaction of his players following their Champions League elimination, was sufficiently pleased to put it down as one of the proudest days of his career.
But Guardiola insisted that it was ultimately his failing and that his responsibility was to teach his players to play his way.

"We play better when the team is down", Guardiola explained.

Guardiola, who spoke to the referee on the pitch at full time, added: "Monreal said he touched the ball with his hand. It's about where they want to play".
"I could not imagine the generation of [Frank] Lampard, [Michael] Carrick, [Paul] Scholes, [Steven] Gerrard, [John] Terry, [Rio] Ferdinand were not able to do something more", he said. Both sides had moments of quality, both were making mistakes, neither was noticeably better than the other, but it was City who twice had the lead and twice threw it away.
"Arsene will remain the best manager in the history of Arsenal forever", said Guardiola.
