"Don't ask me about the attitude of these guys," said Guardiola. "You still doubt what they have done. These players have won seven titles in the last eight [domestic] competitions.
"Today, after missing the penalty, see the reaction we had against an incredibly good team, not just for where they are in the table right now but the way they played, in general, this season. It was an incredible test for us."
Leicester manager Brendan Rodgers, speaking to BBC Sport: "We're obviously very disappointed not to get something from the game. We had big opportunities. Of course you have to defend well, too. You're going to get moved about at times, but I thought we did very well."
On the two handball incidents: "Manchester City's was a penalty. Kasper makes a fantastic save, but ours is clear too. Everyone bar Kevin's arms are down. I believe this was one of the reasons VAR was introduced.
"VAR is fine, it's the interpretation of it. That's what needs sorting out."
Manchester City manager Pep Guardiola, speaking to BBC Sport: "Leicester are a top side. It was a good performance. We didn't give up and that's an incredibly good sign for us.
"We have missed four penalties in a row, but maybe we will score a penalty when we need it to win something. The keepers are good too, but the next one we are going to score."
On Champions League opponents Real Madrid: "The preparation after 12 days off was good. We have played two good games and it's good to prepare for Real Madrid with these good opponents. We are playing the kings of the competition. We will see, we will try to enjoy it and do our game."
