The Norwegian volleyed home Kevin De Bruyne's ball into the back post to open the scoring inside 20 minutes, handing City a one goal advantage heading into the break.
Number two followed before the hour, when Foden jinked the ball onto his left foot before firing into the bottom corner, before the midfielder turned provider for Haaland's second.
And a dominant display was capped off when Dias tapped home our fourth from close-range in stoppage time.
