In a remarkable season for the Citizens, the Premier League, FA Cup and UEFA Champions League all found their way to the Etihad Stadium.
But Guardiola's side have already been knocked out of the Carabao Cup this term and suffered rare back-to-back defeats in the Premier League prior to the international break.
A 2-1 win over Brighton and Hove Albion last week saw them get back to winning ways but Guardiola knows his side are not firing on all cylinders yet.
The City manager said: “The treble had an influence on all of us, me included.
“So now we need to be there, close, month by month, to arrive in the final decision moments at the end of the season close to the opponents to try it again.
“I said many times, no-one has won four (Premier Leagues) in a row, never ever. That shows how difficult it is, but now it’s important to be there, especially in the Champions League, qualify for the next round in this period and after we can just focus on the Premier League. That is the target.”
