The Toffees willingly soaked up 71% of City possession but restricted Guardiola's side to few chances and scored with four of just six attempts at goal.

Romelu Lukaku coolly side-footed in a Kevin Mirallas cut-back and the Belgium internationals combined again after the break, Mirallas drilling Lukaku's through-ball across the keeper.

Tom Davies sent Goodison Park into raptures on just his second league start by dinking a third over Claudio Bravo and £11m debutant Ademola Lookman fired between the legs of the keeper in injury time.

Goals from the two teenagers left Everton boss Ronald Koeman visibly elated, while Guardiola cut a frustrated figure, remonstrating with the fourth official late on in what is his heaviest ever league defeat as a manager.

City lacked cutting edge throughout, though had Davies not headed a looping Bacary Sagna header off the line before half-time, they may not have gone on to suffer a fifth league defeat of the season.

They stay fifth, 10 points off leaders Chelsea, while Everton remain seventh.
