Jurgen Klopp is a quote machine. He's a media darling that says a ton of humorous and enlightening things that get printed in newspapers and published on the internet. The new Liverpool gaffer may be maturing as he gets older and realizing that every single thing he's ever said will stick with him forever.
During his time at Borussia Dortmund he was once asked to compare his style with that of Arsenal's manager Arsene Wenger and had this famous quote:
"He likes having the ball, playing football, passes. It's like an orchestra. But it's a silent song. I like heavy metal."
So, of course at some point during his Liverpool tenure he'd inevitably be asked about this quote. At his pre-match press conference before the club's Europa League clash with Rubin Kazan, he was asked about 'Heavy Metal football' and had this amazing response:
Klopp, asked about heavy metal football, : "The problem with my life is that I've said too much shit in the past and no-one forgets it."— James Pearce (@JamesPearceEcho) November 4, 2015
So, in summation: Klopp gives another dynamite quote in reference to all of his other great quotes in the past. He's the best.
