City have spent more than £200million rebuilding their squad over the summer after an underwhelming and trophy-less 2016-17 campaign.
The Citizens had to settle for third in the Premier League after failing to launch a serious title challenge and their Champions League hopes ended at the last-16 stage.
Guardiola has strengthened his defence this summer, bringing in three younger full-backs in Kyle Walker, Benjamin Mendy and Danilo, and a new goalkeeper in Ederson - as well as signing midfielder Bernardo Silva.
With the core of the squad also likely to be better after a year attuning to Guardiola's methods, the Spaniard has high hopes.
He said: "I think if you see the team last season and this season, (from) the four (pre-season) games we played, the fundamentals are the same. But we cannot forget that when we do something better than last season it's because we've been one year together.
"We know better, I know better and they know me better. Hopefully the work we did last season - when being champions was not possible - we can see it this season because the work is done. The new players that come in they have to adjust to the way we want to play.
"Last season, in the early period, people know how fantastic we were. We won 10 games in a row.
"The fundamentals are completely the same. We try to make a good build-up, try to do high pressing, monopolise the ball, move the team through the ball, attack outside and inside.
"It's completely the same, because it's the same manager. The difference is the quality of the players."
