The result leaves City now seven points behind Premier League leaders Arsenal, though with a game in hand.
Guardiola said afterwards, "Still many games to play, them one less. Now it’s Newcastle (in the FA Cup) and I always think about what’s next.
“If we analyse then in general it was a good performance and there were many good things. Of course we have things we can improve but in general pretty good.”
It was a frustrating evening as City were twice pegged back and dropped points from a winning position.
“There are games that maybe we don’t deserve it but today we play in general good for more than 90 minutes,” Guardiola added.
“Okay you cannot stop the transition or long balls - it’s not about this action or the other action, in general we played well.
“They were so defensive and are a really good team. We were dynamic.
“Maybe we miss contact with Erling (Haaland) and his incredible movements, we have to look for him a little bit more. But apart from that, in general it was okay.”
On Erling Haaland's denied penalty shout, Guardiola added: “Always I believe we have to do it much better to make sure the officials don’t intervene.
“It’s our responsibility to be better. If we have to rely on them it’s impossible. Nothing more to say.”
