The celebrations in Old Trafford's away dressing room could be heard in Liverpool after the Reds smashed five goals past Manchester United.
That is the amusing verdict of Jurgen Klopp's assistant manager Pepijn Lijnders as he reflected on a historic victory away victory over the club's bitter rivals.
Naby Keita and Diogo Jota put Liverpool 2-0 up just 13 minutes into the Premier League encounter before Mohamed Salah continued his sublime season with a record-breaking hat-trick.
Thrashing United 5-0 sent the away fans into frenzy and the party atmosphere was mimicked after the visitors disappeared down the tunnel after the full-time whistle.
Lijnders compared the noise in the dressing room to that of the Wanda Metropolitano, Atletico Madrid's palatial 68,000-seater stadium, in full voice.
Liverpool travelled to the Spanish capital in the midweek before facing United and assistant manager Lijnders said: "You know at Atletico when they scored to make it 2-2, everybody who was there knows the sound of the stadium in Madrid.
"The sound in [our] dressing room was like in Madrid when they scored to make it 2-2!
"I don't know who bought the new speaker, but we have a new one and I think they could hear us in Liverpool!
"As the gaffer says, I don't want to make it bigger. But it was a big one."
Liverpool experienced the full impact of the Wanda Metroplitano atmosphere as they edged out the La Liga champions to a 3-2 victory in the Champions League.
The Reds surged to an early lead but it was far from plain sailing as Antoine Griezmann scored twice to haul Atletico back on level terms, prompting the deafening noise Lijnders referenced.
Griezmann was then given his marching orders for a high boot on Roberto Firmino and Salah converted a penalty to maintain Liverpool's 100 per cent record in Group B.

The Reds are understandably full of confidence after victories over Atletico and United. But, as Lijnders alluded to, Klopp ensured celebrations at Old Trafford were respectful despite the magnitude of the scoreline.
"The result is insane, I asked if there was one like this in history and if there isn’t then it will take a while," said the Reds boss. "The players put a nice piece in the book.
"It is special but we don’t celebrate like crazy, we have respect for the opponents. We were lucky in some moments, United are not in their best moment."Read More Read More
