Arsene Wenger designed the Arsenal dressing room himself to avoid having to shout at his players, reveals Perry Groves.
The former Arsenal player currently hosts the stadium tours at the Emirates and knows all the ins and outs of the design.
Wenger is known for his involvement at every level of the club in north London but took it to another level when he took charge of designing the home dressing room.
The Frenchman isn't keen on shouting at his players–ironically he reportedly went crazy at halftime on Saturday when Arsenal were trailing Liverpool 4-0–and had a special system fitted so he wouldn't have to raise his voice.
It's a snub towards the tactics of Manchester United manager Sir Alex Ferguson who was famed for his "hairdryer treatment" after disappointing results.
Despite Ferguson's success at Old Trafford, Groves admits Wenger doesn't believe in the Scotsman's motivational tactics.
Speaking to talkSPORT, he said: Arsene designed the whole dressing room. It's a massive room... there are seven different areas.
"He’s not a Fergie hairdryer man, he thinks if you lose your temper, you lose the clinical thought process. So there’s a special acoustic that’s been put in the ceiling so his voice will travel [across the room].
"The Arsenal dressing room is huge but if someone is sat at the back they can still hear what he’s saying."
Despite the fact that Wenger doesn't like to shout, Groves admits that the tactician probably lost it during halftime at Anfield alongside assistant Steve Bould.
"I can guarantee you at half time he would not have needed an acoustic system," Groves said. He would have been ripping into them; sometimes it has more of an effect.
"I would like to think that Steve Bould had a couple of them by the throat up against the wall as well."
