Jurgen Klopp has refused to publicly criticise Mohamed Salah after the Liverpool forward tested positive for Covid-19 days after attending his brother's wedding.
Salah attended the ceremony while back in Egypt for the national team's back-to-back Africa Cup of Nations qualifiers against Togo.
Footage from the event appeared to show little regard for social distancing, while few in attendance were sporting masks.
Salah has subsequently tested positive for coronavirus multiple times, precluding him from both Egypt fixtures and delaying his return to England until Friday, when a medically equipped private plane was able to safely carry him.
The 28-year-old will miss this weekend's meeting with top-of-the-table Leicester City as a result, with duration of his absence set to be determined by the date he first provides a negative test.
Asked about the situation at his press conference to preview the Foxes' visit to Anfield, Klopp opted against castigating his player's actions.
He did, though, intimate that private discussions had taken place where he may have been less generous.
"Mo is probably back today, I've heard," he said. "We are in close contact with him all the time.
"It's only when you have a negative test the process really starts. He feels well, no symptoms.
"There is absolutely nothing to say in the public about the things I talk to my players about. What I can tell you I was in the summer in Germany, a friend moved his birthday party only because of me.
"Fifty people attended there and I decided at the last minute not to go – an that was only a birthday party and it was allowed in Germany. It was outside but I didn't go.
"That is only one situation. In other situations there are more social pressure on you and a brother's wedding is a very special moment.
"What I can say about my players is they are incredibly disciplined. All players are incredibly disciplined; there were some cases of course, but they really know about the situation.
"Sometimes it doesn't work out like this and something happens and now we are in the situation we are in.
"All the rest is between Mo and me - we have done that already. We are fine."
