Saido Berahino scored twice as West Bromwich Albion made it back-to-back Barclays Premier League wins with a routine 4-0 defeat of Burnley.
After last weekend's surprise success at Tottenham Hotspur and a League Cup victory over Hull City, Alan Irvine's side maintained recent momentum on Sunday thanks to goals from Craig Dawson, Berahino, who was also on target twice against Sunderland on the opening day of the season, and Graham Dorrans.
That Albion's first two goals came as a result of disappointing Burnley defending from corners will give manager Sean Dyche plenty to ponder, especially as the Lancashire club travelled to The Hawthorns on the back of three straight clean sheets.
Albion played with more freedom in the second half. Berahino's speed and clinical finishing soon put the match beyond doubt with his side's third after 56 minutes, with Dorrans also on target late on.
On the evidence of Sunday's encounter, Dyche has a big job on his hands to keep his side in the top flight, while West Brom celebrated a second Barclays Premier League win of the campaign.
West Brom's starting XI was unchanged from last weekend's win at Spurs, while Burnley, who were again without injured trio Danny Ings, Sam Vokes and Matt Taylor, brought in former Albion player Steven Reid in a holding-midfield role, Ross Wallace and Michael Kightly to replace Marvin Sordell, David Jones and Dean Marney.
The visitors had an early penalty appeal turned down when George Boyd's cross struck Andre Wisdom on the shoulder, but otherwise offered little in attack and tried to focus on keeping it tight at the back.
Their resistance was broken after half an hour, though, when Dawson climbed high above Jason Shackell at the back post to head in a Chris Brunt corner for his first Albion goal since joining from Rochdale four years ago.
Tom Heaton had to be alert to stop Albion from going further in front when tipping a long-range Dorrans strike over the bar.
But a second goal for the home side did arrive in first-half stoppage time when Berahino nodded in from close range after Dorrans had flicked on a James Morrison corner.
Dyche reacted at the interval by bringing on Ashley Barnes and Nathaniel Chalobah for Reid and Wallace.
Chalobah's first taste of action earned him a booking for a lunge on Craig Gardner, who soon after went close with a long-range strike, while Stephane Sessegnon's volley was well blocked by Ben Mee as the hosts continued to dominate proceedings.
And good work from Brunt and Dorrans then put Berahino clean through on goal and he fired low past Heaton on 56 minutes to make it three.
West Brom goalkeeper Ben Foster was forced to make a smart save after Lukas Jutkiewicz rose above Dawson and headed powerfully on target and Barnes might have done better when set up by third substitute Sordell.
Dorrans made it 4-0 after 90 minutes following good work down the right by substitute Cristian Gamboa, neatly tucking his low shot past the outstretched Heaton to move up to 10th place in the Barclays Premier League standings and send Burnley bottom on goal difference.
West Brom head coach Alan Irvine: "I said a few weeks ago I felt we were getting closer to where we need to be. We've still got lots to do but it's been a great week and the players got their reward for the work they've done.
"I've been happy with the way the lads have worked from day one, I believe they will continue to improve but I know how hard it's going to be. We won't get carried away, it's a good start but we have to build on that."
"Berahino’s movement for such a young player is very good. He's a great professional, he’s been a pleasure to work with and he’s got a great future, If he keeps playing like that then he’ll get his reward and Roy [Hodgson] will put him in [the England squad]."
Burnley manager Sean Dyche: "It was a performance where we never got started and never got to grips with the game at all," Dyche told Sky Sports. "It was a real low day for us performance-wise.
"There is a reality to it. We've seen other results like this in the Premier League, now one's happened to us it's important we react and learn from it very, very quickly."
"We've handled most of the games quite well, there were a few changes that were forced upon us but it's important that we have a squad that can deal with those changes and we didn't do so well with that today.
"It makes things tougher as the lads have learned to operate with them in the team, but you want players to come in and take their chance.
"Instead, we concede two horrible set-pieces, from our point of view, and then it's uphill from there."
