The midfielder felt it was in keeping with other "nervous" Champions League displays that mean City are not yet a "big team".
When asked about his tactics at the Tottenham Hotspur Stadium, he said: "It doesn't count if the decision was good or not after the game; nothing changes". I know how hard it is in the Champions League, away at Tottenham and we made a good performance.
"We had a plan, the players knew it and we spoke with everybody about it (before the game) and we did it quite well", he stated. We did it quite well.
"That's true (it is a risky game)", said Guardiola.
Roy Hodgson has warned Manchester City that they need to take the challenge of Crystal Palace seriously when the reigning champions visit Selhurst Park on Sunday. We didn't want to concede a counter-attack, where they are stronger than us. Like in Schalke, where we were winning 1-0 and in five minutes we conceded two. That's why we made a decision to play a different type of game.
"It was about trying to make sure there was a good enough result to go back to the second-leg".
"Of course we want to do well, especially in the Champions League but in that case in this specific game I don't think I agree". I do not agree with what Ilkay says. "After the penalty, Sergio reacted incredibly well and was mentally strong and the team was stable".
Last season, Palace ended City's record 18-game winning run last season but Guardiola's team still amassed 100 points as they cruised to the title.
Guardiola is wary of the threat Roy Hodgson's side will pose, warning: "We knew it from weeks ago - Selhurst Park is always hard; not just for the stadium but the quality of players they have".
They play the Eagles before Liverpool host Chelsea at Anfield. But we have six games left to finish the Premier League, and we know what we are playing for.
