The Premier League clash at Stamford Bridge swung on the stroke of half-time when the Danish centre-half saw red for an agricultural grab on Sadio Mane.
Christensen was first shown a yellow card by referee Paul Tierney, but it was upgraded to a straight red after the official watched it back on TV pitchside.
While Liverpool were the dominant side in that first half, Frank Lampard’s Blues were well in the game at 0-0.
Mane was through on goal after a sublime pass from Jordan Henderson before last-man Christensen hauled him down.
French football journalist Julien Laurens reported that as Christensen was dismissed, “the Liverpool players in the stands clap and sort of celebrate”.
This reportedly left the German gaffer furious, who turned around and shouted: “Are you crazy? We never ever do that, ok.”
Speaking after the game Klopp, 53, explained more about the incident.
He said: “It was not one of my subs but another member of staff and I told him already what I think about it and he’s good with that.
“But in the moment that’s something I don’t want to see.”
We must admit that this is good leadership behavior, kudos to Klopp for his commendable coaching ethics.
