Guardiola was criticised after City squandered a two-goal first leg advantage against Monaco as they crashed out of the Champions League following a 3-1 defeat in France on Wednesday. "Today it was not", Guardiola said, after City became the first team in Champions League history to be eliminated after scoring five goals in the first leg of a knockout tie.
Leroy Sane's goal looked to have sealed a place in the quarter-finals for City however Tiemoue Bakayoko's late header denied them.
Al Mubarak told Guardiola he realised how hard it is to win the Champions League, and the coach added: "I know better than him how it works so when results happen, we are always going to take a decisions".
Liverpool have struggled all of 2017, but they have won three of their last four Premier League matches, including wins against Arsenal and Tottenham, so they'll be hoping their 2017 struggles are over.
But despite being on course for the worst season of his managerial career, Guardiola insists he has the full backing of chairman Khaldoon Al-Mubarak and feels more powerful than ever.
With 10 games left to play, the Merseysiders find themselves in the midst of tussle for the top four. Monaco are flying in the league and in the Champions League, too. We know that it's possible to win. That is what I have to try to convince my players of. What better way to respond is there than beating the team just below us?
I thought we had a few other games in which we were much better than these games, but in this kind of defending, not letting them do what they like to do, what they're used to doing - yes, we have some ideas, if you want. "He's in a really good way".
"Jurgen Klopp will have studied Monaco's approach to beating City and concluded that it was not so very far removed from his own preferred modus operandi - an approach which earned Liverpool a thumping win at City last season".
"They might have a contract and you have to pay their salaries". We are thinking to getting better and that is going to happen.
I saw that I was a little bit in front, and I managed to take it well and put it in the corner.
"It's hard for any of the big clubs to go and win the big tournaments when they're conceding as many as City have".
Not for the first time this season, Manchester City have been let down by their poor defence.
Hopefully! No idea, could I change the time [of the game]?! No! "I tried, I tried - and I will try again", said Guardiola.
"We dominated a club who is second in the Premier League".
"City have a team that is good enough to win the Champions League, which is why our joy is even greater".
