Salzburg have also been charged by UEFA over the throwing of objects by supporters during the game, in which Mohamed Salah struck the victor for the Champions League holders after the Austrian side recovered from three goals down to level at 3-3. Salzburg released a video of Marsch's inspiring halftime talk.
Salzburg brought the game back to 3-3 by the hour, before Salah eventually put the game beyond them by scoring his second goal 21 minutes from the end.
But Klopp was having none of it, and said he wouldn't be happy if his club uploaded a video of his team-talk.
"How many fouls have we got?" "That's the truth and that's all I have to say about that".
It was Marsch's second Champions League game, after becoming the first American to manage in the world's premier club competition with a 4-0 win over Genk last month.
"Everyone wants to panic and stress and maybe look for all the negatives but we shouldn't", said Van Dijk.
A group of youngsters then came onto the pitch at full-time in a bid to get hold of a shirt from one or more of the Liverpool players. Be more ruthless against Van Dijk, we play with too much respect - too much respect.
'Are they strong? Yes. We knew before the game that they would never give up anyway, and they kept going, they had a lot of pace and pressing - a bit like how we play.
"We saw they're good". Come on, guys! We can do more.
Defending Premier League champions Manchester City have also had cameras following them, with the "All or Nothing" series fortunate enough to capture their record-breaking title win in 2017/18.
It's something every fan would love to see, but supporters will simply have to use their imagination about what a Klopp team talk would be like - especially if Liverpool were trailing 3-1 in a match.
