Liverpool manager Jurgen Klopp has cautioned fans of the club to avoid a repeat of the incident that happened in the tie against Manchester City in Anfield earlier in April.

Manchester City's team bus was badly damaged by objects thrown by supporters in the street as they arrived for their Champions League quarter-final first leg, while two police officers were injured.

Liverpool hosts Roma on Tuesday in the semi final first leg, and Klopp has advised the fans to drum their support inside the stadium and avoid clashes outside.

"I think that is really clear, in the stadium do it again and better. Outside the stadium, please show the respect we have to show.

"This is such a fantastic football club, such an outstanding football family known for fantastic atmospheres around the world, so we don't need to throw whatever at the bus of the opponent's team.

"Please show them [Roma] the respect they deserve," Klopp added. "We are only opponents on the pitch, that is the game. This wonderful city can show everyone how wonderful it is.

"We can show how wonderful Liverpool people, the city and the spirit of the club are, 20 minutes before the game and then the whole world knows it."
