The best way is to feel this kind of pressure.
Speaking on Monday, he conceded they are a long way from matching the continental success of the likes of Liverpool and Manchester United, who have eight titles between them, even though he insists they are eager for success.
"We gave away the first penalty, we gave away the second penalty, we gave away the red card".
"We are teenagers in this competition that's my feeling".
"It's not an excuse - we want to win it, we push ourselves and it will be not good if we don't go through".
"You have to dream and point as high as possible but in the same time you have to accept there are other teams thinking the same with a lot of quality and lot of talent".
Along with the suspended Otamendi, Fernandinho will again miss out through injury, but the Brazilian's absence has not been felt as badly as first feared due to Ilkay Gundogan's form.
"The situation in the league is precarious but nevertheless we are going to try with all our effort tomorrow", he said. I prefer this score. "We still have a job to do". If you want to say one day the guy on Twitter says I am going to train in the United States of America and then, after, on the pages of the newspapers I am going to train in the United States of America...what can I say?
Real Madrid, victor for four of the past five seasons, is already out, as is free-spending Paris Saint-Germain. That is my feeling. The Argentine would only likely be used in the 4-2-3-1 option which could see Pjanic on the bench.
And Guardiola said City would be taking nothing for granted going into Tuesday's clash with Schalke. It's incredible what they have done. I'm not too much concerned or anxious about what people say if we win the title just because (of) what happens now with UEFA (and) they do not give us credit for what we have done.
"Hopefully we can be in the quarter-finals but the teams will be of a similar level to Real Madrid because they are top".
Juve will also be up against one of the competition's best-organized defenses and Allegri will be without two full backs because Mattia De Sciglio is injured and Alex Sandro suspended. That's why we have to be focused. "Nobody expected it. And a young Ajax team who went to Madrid".
