Merseyside police reported several people were injured during celebrations and fireworks were fired at the city’s iconic Liver Building, causing a small fire, with police involved in a number of clashes violent.
Thousands of people also gathered in front of Anfield stadium on Thursday after Liverpool was confirmed champion of England.
“I am a human being and your passion is also my passion, but the most important thing right now is that we don’t have these kinds of public gatherings,” wrote Klopp.
“We owe it to the most vulnerable in our community, to the health workers who gave so much and whom we applauded, and to the police and local authorities who help us as a club not to do so.
“Please – celebrate – but celebrate in a safe and private setting, by which we do not risk spreading this terrible disease further in our community.”
“Please stay at home”
Over the weekend, Liverpool mayor Joe Anderson reiterated his call to supporters not to rally and said he had been frustrated by those who ignored warnings from the club, health experts and authorities .
“I say what I say in pain rather than in anger, because people’s lives, your life, their lives are threatened.”
The club has repeatedly asked supporters not to assemble outside the stadiums before, during or after the remaining matches.
Liverpool will face Manchester City in the Premier League on Thursday before returning to Anfield to play against Aston Villa on Sunday.
Klopp promised fans that they would have a chance to celebrate with the team someday, but only when it was safe.
“When the time is right, we will celebrate. We will take advantage of this moment and paint the city red. But for now, stay at home as much as possible,” he continued.
“This is not the time to be in the city center in large numbers or to go near the football fields.”
He added: “I already knew and loved the German word solidarität before I came to Liverpool and now I have learned that the English word is solidarity because I have heard it used by our supporters over the past few months.
“To me, it’s the word more than any other word that captures what the people of Liverpool are. That’s why they came together to make PPE, that’s why they delivered food and medicine packages to people when they needed it most and that’s why they’re coming together in so many different ways during such a difficult time. “
