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.
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.
