The Catalan, who came to England in 2016, made history by following a 2017-18 season which saw City claim 100 points with the club's first domestic treble, winning the Premier League, FA Cup and EFL Cup in the same campaign.
However, following eight Premier League outings this season, City find themselves eight points behind leaders Liverpool in the wake of Sunday's 2-0 defeat to Wolverhampton Wanderers.
In an extract released by The Sun from his new book, 'Pep's City: The Making of a Superteam', Guardiola said: "[City chairman Khaldoon Al Mubarak] knows I'd step aside if things weren't going to plan.
"I'll give everything to avoid that and make every effort to move things forward. No coasting."
