The midfielder was awarded Man of the Match for a dominant display in a baking hot Etihad Stadium, where City were a class above our newly promoted opponents.
Turning from scorer to provider, De Bruyne teed up Foden to grab our third before half-time, with a late Jefferson Lerma own-goal rounding out the goals as we sealed our second win in two Premier League matches.
Despite our dominance, the Belgian international insisted there was more to come from the defending champions.
"Obviously the circumstances are hard, it's so hot, the pitch wasn’t great which makes it all the more difficult," he said.
"But leading 3-0 fairly quickly in the half makes it easy and even in the second half they were defending so deep.
"We didn’t give too much away but I think we can still go up a level."
On his goal, De Bruyne remarked: "He (Lloyd Kelly) was backing off and he was closing more the outside so I saw the little gap, tried it and it went in.
"When I was young I tried everything and I got told off a lot of times.
"It’s important to do inside and outside with both feet because it can help and today it did help."
