A stunning six-goal blitz from Brisbane delivered Justin Leppitsch’s men their sixth win of the season over a wayward Melbourne side.

A meeting of Melbourne and Brisbane never promised finals-quality football but Justin Leppitsch was staggered by how bad it was.

“At three quarter time I said ‘this is the worst game I’ve ever seen’,” Brisbane coach Leppitsch said.

He wasn’t alone as Brisbane battled to a 11.8 (74) to 6.15 (51) win, with beaten coach Paul Roos joining the boo brigade.

“It was as frustrating a game of footy as I’ve ever seen,” Roos said.

“I haven’t seen anything like that before… the mistakes were extraordinary.”

While the match was a close contest throughout, poor foot skills and decision-making made it one for the die-hards.

The teams had just five goals each at the last change before Brisbane kicked the final six goals of the contest to win by 23 points.

The Demons had control of the ball for much of the match but kicked just 1.5 in both the second and third terms for a narrow lead at three-quarter time.

Daniel Merrett, who was reported for striking Cam Pedersen with his forearm in a marking contest, Jed Adcock and Michael Close first erased the Lions’ deficit.

Daniel McStay, Ryan Harwood and Lewis Taylor then kicked Brisbane to a 23-point win, their sixth for the season.

An exasperated Paul Roos was able to pinpoint the reason behind Melbourne’s loss.

“If you can’t handball five metres to a teammate, it’s impossible to move the ball,” he said.

“I didn’t see them lack adventure, I saw them not be able to kick it to each other.”

Roos then gave a tough mental assessment of his young side, who extended a losing streak at Etihad Stadium to 19 games.

“There’s clearly some who might not be able to get over what’s happened here in the past,” he said.

“I think we’re a team that’s waiting to get beaten.”

“I don’t think we play to win.”

He suggested some players would be playing for their futures in the next month, with “tough determinations” to be made after the final four games of the year.

While Leppitsch was down on the game’s quality, he did praise his team’s endeavour.

“I thought our consistency of effort was there the whole game,” he said.

“There were little things that let us down, technical things that we can fix.
