On the back of a clean sheet from the heavily-criticised Joe Hart in the wake of his poor performance against Cardiff, second-half goals from Alvaro Negredo and Yaya Toure were enough to see off the Tigers.
For Negredo, a £20million summer buy from Seville, it was his second goal in two matches after his late strike in south Wales, and again after coming off the bench.
The Spaniard opened the scoring in the 65th minute with a close-range header, but it was not until the 90th City finally made the game safe via a stunning free-kick from Toure.
Remarkably, as with the opening 45 minutes at the Etihad, the four 3pm kick-offs also failed to produce a goal.
Looking to follow up on their triumph over Manuel Pellegrini's side, Cardiff barely mustered an opportunity on home soil against Everton.
Instead, it was the visitors who were denied a shot at taking the lead when Leighton Baines was brought down in the area by Gary Medel, only for referee Anthony Taylor to wave play on.
There should arguably have been a penalty, too, at Carrow Road when Bradley Johnson handled a shot from Southampton's Adam Lallana, but Howard Webb was unmoved despite a clear sight of the incident.
To even matters up, Webb later dismissed shouts from the Canaries when a Ricky van Wolfswinkel header hit the hand of Calum Chambers.
Lallana later tried his luck with another cracking drive, only to be denied by the post.
At Upton Park, West Ham goalkeeper Jussi Jaaskelainen was one of the busiest players on the pitch in an opening half dominated by visiting Stoke.
Jaaskelainen was forced into making key saves from Charlie Adam, from a 25-yard free-kick, Marc Wilson from a long-range volley and then Jonathan Walters on the follow up.
In the other game at St James' Park, Newcastle had the edge over visiting Fulham, but despite a couple of chances for Papiss Cisse, there was again no breakthrough.
