Manchester City's £100m man Jack Grealish scored on his home debut as the reigning Premier League champions returned to winning ways by thrashing newly-promoted Norwich.
Shaking off three successive defeats bridging this season and last, Pep Guardiola's side assumed complete control from minute one against the outmatched Canaries.
There was some fortune about their first two goals - both set up by low Gabriel Jesus crosses - as Grant Hanley's attempted clearance flew in off Norwich keeper Tim Krul before City's second bounced in off Grealish's knee.
However, the lead was just reward for the imperious hosts, who saw a neat Ferran Torres finish chalked off in-between those goals after the video assistant referee noticed Bernardo Silva's clip on Milot Rashica in the build-up.
