Guardiola's team are expected to break the Premier League record for most wins, goals and points in a single season, and the Spaniard said that it was a great achievement because of the difficulty of the league.
“In England, it’s special because it’s so tough,” Guardiola said, as quoted by City's official website. “We saw that [against Huddersfield] and that’s why but okay, we got it; we did it.
“Here, it is more difficult. Of course, you never know you’re going to win titles – nobody knows – but I didn’t have doubts about what we had to do or what we needed to try to do.
"We started the season believing we would try to do it but I didn’t know we were going to win.”
Guardiola used Sunday's draw as an example of City's potential to keep improving. The Citizens dominated possession and attacked relentlessly in the second half, but couldn't find a way past Huddersfield's resilient defence.
“Today was proof we can do better. It was warm; it was so tough,” he said. “They were playing to stay in the Premier League.
“This week, too many things surrounded the team that meant we missed a little bit of focus but that’s normal."
