Liverpool boss Jurgen Klopp has called on the club's fans to behave ahead of Tuesday night's Champions League semi-final first leg against Roma at Anfield.
Klopp said: "In the stadium do it again, outside the stadium please show the respect we have to show.
"This is such a fantasy club, an outstanding football family, known for a fantastic atmosphere all over the world so we don't need to throw whatever at the bus of the opponent team.
"If we can do what we did creating an atmosphere in front of the stadium then do it but show our opponents the respect they deserve.
"We can show how wonderful Liverpool people are and we can show it in 20 minutes before the game and then the whole world knows it."
