If Borussia Dortmund and Liverpool have one thing in common, it is their vociferous fanbase. The Westfalenhallen is widely regarded as one of the noisiest places to be on a matchday in Europe while Anfield is certainly no library.
But another thing they have in common, as of October last year, is Jurgen Klopp. The charismatic German manager has spent time in charge of both clubs and is currently enjoying a good start to the season with the Reds.
As he approaches his first anniversary on Merseyside, Klopp has already deeply embedded himself into the soul of the club and has caused a surge in excitement and optimism amongst the committed fanbase.
He has already given them some memories that will last a lifetime, such as Liverpool's dramatic comeback against his former club in the Europa League last year or their equally impressive 2-0 victory over Manchester United in the same competition.
However, it pales in comparison to his record at Borussia Dortmund. Klopp won two Bundesliga titles with the Black and Yellow and guided them to the Champions League final as well. Lest we forget, he achieved all of that on a shoestring budget.
And his success was probably aided by the incredible support from the Dortmund fans, in particular those situated on the Yellow Wall. Officially called the Sudtribune, it is the largest terrace for standing spectators in European football and regularly reaches its 24,454 capacity.
The only thing that compares to it is, coincidentally, Anfield's Kop End. At 12,390, it has half the capacity of the Yellow Wall but certainly rivals it for noise, especially on a European night.
Speaking to fans on Facebook, Klopp was asked to compare the two stands and came up with a perfectly diplomatic response.
The Kop vs The Yellow Wall
"It's different, there's nothing compared to the Yellow Wall though," claimed Klopp on Sky Sports News HQ. "There are 27 thousand people who stand.
"The Kop gave me the best half hour of football [against Borussia Dortmund last season] though. It was the best I ever had.
"It was outstanding. I don't want to compare. I'm a lucky guy to have coached two wonderful clubs."
Klopp, who features alongside Jamie Carragher on Monday Night Football, also revealed his long-term ambition for Liverpool.
"Only to play football that people remember," added Klopp. "That's all we have to do in life. Create some moments that people enjoy.
"Of course we want to win the league, but I don't know when it will happen, or if it will happen. But we are not too far away."
