"We have to play more than 45 minutes". It has the coach, certainly the finest of his generation, now Guardiola needs the squad to deliver on his vision - starting at the back.
"It's a massive disappointment". Monaco dominated the first half with their high-pressing causing huge problems to City's defence and stopping them passing through midfield and creating chances. "We gave them too much respect and ... we put ourselves in danger". Monaco couldn't do it two halves. It's the same situation for Pablo Zabaleta, who remained on the bench as City's pursuit of a first European Cup ended in the round of 16.
But, against a Burnley side with just two points away from home this season, Liverpool were forced to work hard to come back after Ashley Barnes had shot the visitors into a shock, early lead.
After winning the first leg 5-3, the Spanish boss made a decision to field an attacking line-up in the return fixture against the French side, which seemingly backfired as City ended up losing 3-1 and being knocked out courtesy of the away goals rule.
Speaking to Sky Sports, the 31-year-old came out with the rather freakish comment that he thinks the current Liverpool team are as good, if not better, than the title-winning sides of Roberto Mancini and Manuel Pellegrini.
Guardiola has built arguably the greatest attacking force now in the Premier League - with Kevin De Bruyne, David Silva, Leroy Sane, Raheem Sterling, Sergio Aguero, Gabriel Jesus and Nolito all top class offensive options - but his defensive unit is remarkably poor.
"Qualification for the Champions League will be tough until the last game of the Premier League", Guardiola said.
City were dumped out of the Champions League by French side Monaco on Wednesday, with striker Sergio Aguero having a rare off-day in front of goal, but Klopp is not banking on another poor performance from the mercurial Argentinian.
It promises to be a mouth-watering clash at the Etihad with third-placed City still harbouring hopes of reigning in league leaders Chelsea with 11 games of the season still to play. But Guardiola said he won't alter his tactics, particularly after City improved massively in the second half. It's an enormous joy, I didn't expect it.
City did start the better team in the second half and maybe should have had more than just a goal to show for it. "But this was not our best game so, yes, if we want to stay where we are, then we need to win football games and we can't make the choice and say "yes or no we want to play this way", the German added.
Don't discount Arsenal from forcing either Liverpool or City from the Premier League's top four.
