Luton Town boss Nathan Jones described Norwich City as the Manchester City of the Championship as Teemu Pukki grabbed his 19th and 20th goals of the season for the runaway leaders, who stylishly dismissed the Hatters for a seventh successive league victory.
The Canaries, who regained their 10-point advantage following Watford's win over Nottingham Forest in the lunchtime kick-off, had an early scare when a James Collins shot hit the post.
But the attacking talents of Pukki, Todd Cantwell and Emi Buendia were too hot to handle for a Hatters side playing with confidence after back-to-back victories.
