Nahki Wells took his tally to six goals this season

Bartosz Bialkowski's goalkeeping howler saw Millwall slip to defeat against Queens Park Rangers at The Den.

The Pole missed his clearance kick and the ball ran free for Nahki Wells to roll the ball into an empty net.

It was Wells' second of the afternoon as his first, 11 minutes into the second half, had given Rangers the lead.

Two minutes later Shaun Hutchinson scrambled home an equaliser from a corner before Bialkowski's error helped restore QPR's lead.

Victory was QPR's fourth league win in a row and lifted them to fourth in the Championship, thanks to Wells' fifth and sixth goals of the season.

His first was a left-foot shot into the bottom-left corner after a strong run into the penalty area but the second followed a stroke of pure fortune.

Bialkowski failed to clear and was left stranded as the loose ball was pounced on by Wells to turn in the simplest of finishes.

Jed Wallace spurned a chance to equalise 10 minutes from time as he shot wide from the top of the penalty area as Millwall suffered their first home defeat of the season and are now five games without a league win.

Millwall boss Neil Harris:

"Goals change games. One minute you're in the ascendancy thinking here we go, 20 minutes to go at The Den, a London derby, the fans have found their voice, we've got pressure on them, then we make an error like Bart's and the game's gone.

"I feel for Bart, he's a good lad, a good pro, a good goalkeeper, but that's football, isn't it?

"We were getting our noses in front and got back on level terms - I thought we deserved a point out of the game.

"Maybe I have to look at myself for a little bit more consistency - I've never been a manager that tinkers with a team.

"I decided to because I thought the players deserved the opportunity. But if the players aren't going to perform, then they don't deserve the opportunity to play."

QPR boss Mark Warburton:

"You earn your luck. We've given soft goals away ourselves in recent games, and that's the nature of the league, you hope over the course of a season they even themselves up.

"I thought we were the better team first half, missed a couple of big chances, but came out and got the goal early.

"We're creating chances, you'll see that in the stats from all the games, even when we've dropped points we've created numerous chances.

"What we have to do is put them in the back of the net. There's games you play really well and don't win, and games you play poorly and come away with a point or all three points."
