City are now eight points behind Liverpool after their 2-0 home defeat to Wolves on Sunday.
Discussing his close relationship with chairman Khaldoon Al Mubarak in ‘Pep’s City: The Making of a Superteam’, Guardiola said: “He 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.”
The book, written with Pep’s authorisation, also reveals he will impose a Christmas curfew this year after he was reported to be furious some of his players stayed out until dawn after last year’s festive party at the Great Northern Warehouse.
Their shock 3-2 home defeat at the hands of Crystal Palace followed soon after on December 22, 2018.
And while most reported for training on time, some had clearly overdone it — and Guardiola was fuming.
The new book, out later this month, also tells how the Spaniard introduced a roulette wheel to discipline players.
He told them: “No more fines. Now, if you mess up you spin the wheel and find out what you have to do to compensate the team.”
Punishments include helping kitmen, groundsmen and kitchen staff — with Benjamin Mendy reported to have several sessions in the club laundry room.
