Many fans and pundits are expecting last season's top two to battle for the title this time around as well.
However, Guardiola believes there is so much quality throughout the league that many teams can challenge for the title his side has won in the past two seasons.
"I believe it will be different," Guardiola told Sky Sports News.
"Every team has made a step forward. The standards ourselves and Liverpool set last season, the other contenders have to achieve that, to take on the challenge to win the Premier League.
"Will they be closer? I think so."
