WHEN Burnley roll into the away dressing room at Old Trafford on Boxing Day carrying their 'powerful' sound system they might attract a look of scorn from Jose Mourinho.

Music in dressing rooms has become a talking point since the United boss reportedly took umbrage with the volume of Manchester City's musical celebrations after claiming success in the derby at Old Trafford earlier in December.

Mourinho went to City's dressing room door to complain about the volume but with the Clarets in town over Christmas it's unlikely to get any quieter for Mourinho.

Burnley attracted plenty of attention last term for their pre-match sound thanks to a system brought to the club by Andre Gray, and although Gray has departed his speaker hasn't, with Dyche joking he wrote it into the deal which saw Gray move to Watford for £18million.

And Dyche believes the issue of complaints over stereos has been overplayed.

“There’s no actual debate there, people have been playing music for years," he said. "Nowadays you can imagine the power of those stereos, I don’t know what brought that on but I don’t think it’s anything to do with stereos.

“Andre had a powerful one, he left it, I had it written in the deal, I had to swag it."

In March Michael Keane revealed that his friend and former Manchester United colleague Jesse Lingard had told him Mourinho had been unhappy with Burnley's volume at Old Trafford in October 2016.

"Jesse told me that the manager wasn't happy when we were at Old Trafford. But it worked didn't it?," Keane said.

Recently Wayne Rooney has had his say on the musical debate and he also claimed Burnley were the loudest in the league.

"If you've played Burnley over the last few years, they must have a big music system because the noise coming out of their dressing room before and after games is incredible. It's deafening," Rooney told talkSPORT.

Dyche revealed music hadn't really been a part of the dressing room culture in his younger years at Nottingham Forest but by the time he hung up his boots it was a regular pre-match ritual.

“I mean it sincerely, when I was playing it was in the dressing rooms," he said.

"Funnily enough, when I was an apprentice and young pro at Forest, we never had anything.

“It was really quiet. It would be odd now, players get ready, chit chat, manager comes in, says his thing, go and play.

“It might be a cultural thing, it was in the breakdance films of the late 80s, the ghettoblasters, They started coming on your travels, then they got more slicker and powerful, now they’re iPod docks, bang and off we go.

“I think the first ones to get in the news for it were Wimbledon, and it spread."

Dyche said he didn't tell his players to 'turn it up or down' and he also laughed off the suggestion he could influence the pre-match playlist.

"I don’t get any say here, you kidding?! It’s all bass with 10 words or something," he said.
