Liverpool head coach Jurgen Klopp said preparation for Sunday’s 3-0 home win against Nottingham Forest had been "the most difficult I’ve ever had in my life".

Reds forward Luis Diaz did not feature in the Premier League clash at Anfield after reports that his parents had been kidnapped in Colombia and Klopp said the player had returned home to be with family members.

Liverpool confirmed an "ongoing situation involving the family of Luis Diaz" earlier on Sunday and Colombia’s president said Diaz’s mother "has been rescued" but his father remains missing.

Klopp said: "The game preparation was the most difficult I’ve ever had in my life. I didn't expect that, I wasn’t prepared for it.

"I don’t want to make the game bigger than it was, but definitely, we tried to help Luis with the fight we put in because obviously we want to help and we cannot really help.

"So the only thing we can do is fight for him and that’s what the boys did."

Liverpool secured their fifth straight home Premier League win to move three points behind leaders Tottenham.

But Klopp said: "How can you make a football game really important on a day like this? It's really difficult. I’ve never struggled with that in my life.

"We heard late last night about it. We spoke to Luis, he wanted to go home…Then we got the news with his mum, which is fantastic, and since then nothing really.

"We are obviously the first people to get involved and we try to have knowledge of everything as much as we can, but we don’t want to disturb in any way the important people there, we just want to support, that’s it."

Liverpool said in a statement that they were supporting the player. It read: "Liverpool Football Club can confirm it is aware of an ongoing situation involving the family of Luis Diaz in Colombia.

"It is our fervent hope that the matter is resolved safely and at the earliest possible opportunity. In the meantime, the player’s welfare will continue to be our immediate priority."
