Guardiola’s side dominated proceedings at the Stadium of Light but were unable to break down a stubborn Sunderland defence.
City ended the game having had 68% possession, 14 shots, four of which were on target, and five big chances created.
Bernardo Silva thought he had opened the scoring in the sixth minute, but replays showed that the City captain was offside.
Speaking to Sky Sports after the game, Guardiola said: "Good. Take the point. Second half was excellent. We missed. We could not score in the six-yard box.
"How many times we were in the six-yard box against the keeper or the other one and could not convert. Of course, the threat they have, they are really good. Really pleased with the performances, especially in the second half.
"We create a lot against that team in this stadium, especially in the second half. The first half, we struggled simply because we struggled against their pressing but Rodri gave us the second pass, to break the lines, and we could run. Second half was much better.
"They are so physical. They're so strong, so it's not a surprise at that. We take the point. (It's) a long way.
"The result is always what it is."
