Jurgen Klopp sent Mamadou Sakho home from Liverpool’s pre-season tour of the United States because of the defender’s poor timekeeping.
The Reds did not comment on the reasons for Sakho’s departure from California on Tuesday.
However, Klopp revealed on Wednesday he took action after the 26-year-old was late three times.
Quoted in several newspapers, Klopp said: “He missed the departure of the plane, he missed a session and then was late for a meal.
“I have to build a group here, I have to start anew, so I thought it maybe made sense that he flew home to Liverpool and after eight days, when we come back, we can talk about it.”
Klopp does not believe fining Sakho for his tardiness would be a worthwhile exercise, adding: “I am not interested in the money of the players.
“Not often in my life have I had to fine anybody, because I want that we learn together to do the right thing.
“Always it is the same with every group. I don’t like fining.”
Sakho is currently nursing an Achilles problem which will prevent him starting the new Premier League campaign. Liverpool’s first game is at Arsenal on August 14.
