By Greg Stobart at Etihad Stadium
City had to wait 32 minutes for Sergio Aguero to open the scoring at the Etihad Stadium but secured a thumping victory thanks to second-half strikes from Samir Nasri, Yaya Toure, Mario Balotelli and Adam Johnson.
The result means the Premier League leaders have netted a stunning 48 goals from their 14 matches so far this season.
Platt, however, is adamant he would be more than happy to win every game by a one-goal margin.
“The number of goals we're scoring is irrelevant,” he told reporters after the game. “People automatically assuming we're going to score five or six goals every time we play one of these games, but we would take a 1-0.
“Credit to them, they got people behind the ball and made it difficult for us. It was always going to take a bit of brilliance to open the game up.
“It was a matter of keeping the ball moving, shifting it around and waiting for that bit of brilliance from somebody. We know we've got players who can do that. Every single player has joined in the performances this season.”
Balotelli once again attracted attention by converting his goal – City's fourth – with his shoulder on the Norwich goal-line, but Platt was keen to play down the controversial striker's showmanship.
“A goal is a goal whether you put it in from 30 yards or a foot away,” Platt added. “The ball went in from 12 inches but it was a very well worked goal.”
