Mamadou Sakho was sent back from Liverpool's pre-season tour of the United States because of a lack of respect towards rules but the defender's actions were not serious enough to warrant more punishment, manager Jurgen Klopp has said.
The France international, who was recently cleared by UEFA after allegations of a failed drugs test, is currently nursing an Achilles injury and is expected to miss the start of the Premier League season, which begins on 13 August.
Klopp said Sakho broke rules during the tour.
"He missed the departure of the plane, he missed a session and then was late for a meal," Klopp told British media.
"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.
"But it's not that serious. It is how I said, we have some rules and we have to respect them. If somebody doesn't respect it, or somebody gives me the feeling he is not respecting it, then I have to react, that's all."
Klopp said there was no falling out with Sakho and it was unlikely the club will fine the 26-year-old.
"We had no argument. I spoke. You cannot argue when only one person is speaking, that's all," the former Borussia Dortmund manager said.
"Always it is the same with every group. I don't like fining. Sometimes it's funny, when the fine is bullshit. Come on, pay for it, that's nice. But mistakes, fining never helps."
Liverpool, who finished eighth in the league last season, will start their campaign with a trip to Arsenal.
Klopp meanwhile is happy with the way the club's 'democratic' transfer policy is structured.
The German is used to working with a sporting director from his time at Mainz and Borussia Dortmund as the model is common in his homeland.
Liverpool's much-criticised transfer committee, a source of frustration for former boss Brendan Rodgers, has been re-evaluated and revamped since Klopp's arrival with the 49-year-old having the final say on all deals.
But that does not mean Klopp is against an all-round approach to sourcing and securing targets.
"Improvement can come in all kinds of life and in all parts of life and it's based on experience," he told ESPN FC.
"So I don't think it makes sense that you give one person the whole power, that's why we have democracy and no other kind of political leadership.
"Hopefully it stays like this and because we learned that it makes sense that you put all your skills together and in the end you try to find the best decision.
"I don't know how it works in other clubs but in this squad it's not one player.
"It's all about the situation in the club and the squad and it's about money.
"We all have a budget - (that is) how it is and that's how I like it and that's how I'm used to working.
"So it's a lot of work to find a solution at the end.
"And yeah when I put my thumb up - and I only can do this when the financial things are agreed - and the player joins us or leaves us that's how it is."
