Divock Origi celebrates his goal against Borussia Dortmund
The Reds went 2-0 down after just nine minutes.
But a brilliant comeback saw Klopp's men rally to secure a 4-3 victory (5-4 on aggregate).
And the striker has revealed what Klopp told the players inside the dressing room.
Origi, who was speaking to BT Sport, said: "At 3-0 down and the coach said you have to create the moment where we could tell our grandchildren and children and make it a special night for the fans.
"We believed in it. After the first goal, we felt it would be a special moment.
"You saw at the end defenders scoring and strikers scoring and we deserved the win."
Liverpool will find out their fate when the semi-final draw is made today.
