Schwarz's strugglers secured their Bundesliga status with a well-earned 2-1 triumph at the Signal Iduna Park, roused into action by the recent UEFA Champions League exploits of Mainz and Dortmund old boy Klopp.
Watch: Highlights of Mainz's shock win in Dortmund
"I was so excited by the game and by Liverpool's attacking," Schwarz said of watching the Reds thrash Roma 5-2 in their semi-final first leg. "I called my video analyst straight away and got him to cut and paste all of the clips together."
In true Liverpool style, Mainz flew out of the traps on Bundesliga Matchday 33, scoring twice inside the opening 13 minutes through Ridle Baku and Yoshinori Muto. They conceded before the break, but held on - just as Klopp's lot did in Rome days earlier to book their place in the Champions League final thanks to a 7-6 aggregate win.
Cut from the same Mainz cloth, Schwarz played for his hometown club alongside Klopp from 1997 to 2001, before making 80 appearances under his long-time tactical muse, achieving promotion to the top flight in 2004.
Like Klopp, Thomas Tuchel and Martin Schmidt before him, 39-year-old Schwarz was already on the Mainz books - in his case at the helm of the U23s - when he took charge of first-team affairs on 31 May 2017.
