Burnley striker Chris Wood scored a superb first-half brace to help them outclass promoted Norwich City at Turf Moor in the Premier League.
The result snapped Burnley's four-game winless run since they beat Southampton 3-0 on the opening day of the campaign and gave Daniel Farke's Norwich a reality check following their 3-2 upset of champions Manchester City last weekend.
Forward Wood put Burnley, with Ireland's Jeff Hendrick starting in the middle of the field, ahead in the 10th minute with his first league goal since April, guiding his header past Norwich goalkeeper Tim Krul at point-blank range after Ashley Westwood whipped in a perfect ball from the corner.
Norwich paid the price for giving away possession cheaply as New Zealander Wood doubled Burnley's lead four minutes later by meeting midfielder Dwight McNeil's drilled pass from the left with a crisp left-footed shot that gave Krul no chance.
Midfielder Moritz Leitner, who came on in the opening half for the injured Alexander Tettey, had Norwich's best chance of the game in the 23rd minute but his fierce shot from distance only rattled the post with Nick Pope beaten.
Sean Dyche's Burnley, who have collected eight points from six matches, next travel to promoted Aston Villa while Norwich visit Crystal Palace.
Hendrick was rewarded for his late equaliser as a substitute against Brighton last weekend with a starting spot for the hosts while Norwich, unsurprisingly, were unchanged.
If ever there was a team geared up to dish out a reality check, it is surely Burnley, and the Clarets began with an intensity that Norwich could not match.
