Salzburg came from three goals down to level the scores after half time before Mohamed Salah scored the winner for Liverpool.
It was a brilliant fightback from the Austrian side at Anfield and the video has provided an insight into their dressing room at the interval, but Klopp can’t believe it was filmed in the first place.
He said: “If LFC asked me in that situation, I would leave the club! That is the truth. That is all I have say about that.”
In the video, Marsch told his Salzburg players they were showing the Champions League winners too much respect.
“How many fouls have we got? How many? Maybe two?” Marsch began. “This is not a f*cking friendly! This is a f*cking Champions League match! We need to step up. There is too much respect for the opponent. Too much respect for the opponent!
“That goes for when we have the ball, when we don’t have the ball and for fouls. Too much respect!
“Are they good? Yes, they are good. But we’re playing too nicely, only with a little pressure here and there… There is no real tackle or a fight. They have to feel us, guys. They have to know we’re f*cking here to compete.
