Fresh from an exhilarating Champions League clash with Real Madrid, City hosted struggling Luton Town.
Knowing a victory would take the Blues back to the top of the Premier League for the first time in five months, Pep Guardiola made six changes to the team that started at the Bernabeu.
And City were ahead with just 70 seconds on the clock as an Erling Haaland acrobatic shot struck the face of a Luton defender and diverted into the net.
It would be more than an hour before Mateo Kovacic doubled our lead, with Haaland adding a third from the penalty spot not long after.
Though Ross Barkley pulled one back for the visitors, late strikes from Jeremy Doku and Josko Gvardiol rounded off a 5-1 win.
