Match ends, Wolverhampton Wanderers 1, Burnley 0.
Burnley manager Sean Dyche said his team are "in a bit of a fog" after defeat by Wolves at Molineux left them still waiting for their first league win of the season.
Wolves dominated large periods of the first half, and Raul Jimenez deservedly opened the scoring on the hour mark as he turned in Matt Doherty's cross.
The visitors rarely threatened, with the only real chances they created falling to Johann Berg Gudmundsson late on.
Defeat for the Clarets means they have equalled a club record run of four consecutive Premier League losses.
"Attacking-wise we were nowhere near enough," Dyche said.
"We are in a bit of a fog at the moment. Collectively we need to get out of it. You have to work to change it, so that's the key.
"But we have been down this road before and we've managed, along with the players, to pull out of the fog."
While Burnley are 19th in the table with just one point from five matches, promoted Wolves have climbed to ninth.
In his pre-match news conference, Wolves head coach Nuno Espirito Santo called for his players to "maintain the standards" set in their 1-0 victory over West Ham, and he was not disappointed.
Last season's Championship winners were by far the brighter team throughout, putting Burnley under sustained periods of heavy pressure either side of the break.
They should have gone ahead on the half-hour mark when first Joe Hart superbly denied Jimenez, before James Tarkowski cleared the Mexico striker's second effort off the line.
Moments later, Tarkowski was again alert to clear Jonny Otto's effort after Hart had palmed clear a low cross, and the former England keeper was then quickly out to smother Doherty's sliding effort from close range.
After Jimenez finally found the net midway through the second half, the home side only got stronger, largely thanks to the introduction of Adama Traore after 66 minutes, his pace causing a tiring Burnley backline problems.
The Spanish forward tested Hart before laying on three good chances for fellow second-half substitute Leo Bonatini, who was unable to convert.
Victory for Wolves means their impressive home record under Nuno continues; his side have only been beaten twice at Molineux in his 29 games in charge.
Burnley could perhaps have been forgiven for their poor start to the Premier League season given their Europa League exertions, but after the international break there could be few excuses for their uninspiring performance.
Their midfield was overrun by Wolves' energy, and Ashley Barnes' effort from range, which was easily saved, was his side's only shot on target in the opening 45 minutes.
It seemed to take conceding a goal for the team to kick into gear, and their best chance came shortly after going behind when Willy Boly almost deflected a Charlie Taylor shot inches wide, with Jack Cork unable to apply the finishing touch.
But it could have been worse for Burnley as Doherty fired wide with only the keeper to beat after being set up by Traore, and Bonatini missed several chances.
Gudmundsson, on his return from injury, could have stolen a point late on, but he shot straight at Rui Patricio and fired a free-kick over the bar.
"When there is a fog around the group it can eat into people," said Dyche. "To bring that flow back you have to be strong mentally and physically.
"I think it's a mentality thing. Some of it can be worked at on the training ground, but I call it bottoming out; a collective moment when a group of players bottom out.
"The quicker that comes the better, because sometimes that opens the mind again and it all clicks back in again. You also have to work at that though."
The Clarets have now won only five of their past 26 Premier League matches.
Dyche, however, will have been encouraged by the performances of Hart and Tarkowski, the latter of whom showed why he has fought his way into the England fold.
Wolves head coach Nuno Espirito Santo, speaking to Sky Sports: "I am very, very satisfied. We played good football and stayed organised and created chances. Burnley are a good side and stayed in it until the end.
"If there is a 'but', we could be more clinical. But if we can continue to make these many chances, it makes me very proud."
Burnley manager Sean Dyche: "When we got into the Europa League there was this immediate noise about it being tough. You are bombarded with it and it's hard to deal with that as a group - and then it becomes an easy story when you don't start the season well.
"People ramp it up and say 'there you are, I told you'. Well, we have to find a way through that and I remind them they are roughly the same group of players who finished seventh last season."
Both sides are back in action on Saturday, 22 September. Burnley host Bournemouth, while Wolves travel to Old Trafford to face Manchester United (both 15:00 BST).
