Liverpool and Manchester City has issued a joint statement condemning the "wholly unacceptable" incidents that emerged from Thursday night's Carabao Cup at the Etihad Stadium.
Both clubs had asked for fans to respect the rivalry ahead of a 3-2 win for Pep Guardiola’s side.
The last few years have seen a number of unsavoury incidents occur between supporters, with the latest meeting at Anfield in October marred by offensive graffiti about Hillsborough being written in the away section and allegations of chanting about the 1989 disaster, in which 97 fans died.
City's also claimed coins had been thrown at their coaching staff, although a Liverpool investigation failed to find any evidence, and one of their buses was damaged on leaving Anfield.
Now both Premier League clubs have said that reported incidents from their latest clash will be investigated and reported to the police.
"Liverpool FC, Manchester City FC and the chairs from our supporter groups have worked together in recent weeks to remind fans of our expectations and both clubs would like to thank the vast majority of fans for their behaviour at last night’s Carabao Cup match at the Etihad Stadium," the statement read.
"It is however hugely disappointing that there were a number of incidents during last night’s match that are wholly unacceptable. These incidents will be fully investigated, reported to the police and the individuals who are found to be responsible will be subject to the sanction process of their respective club.
"Liverpool FC and Manchester City FC are fully committed to working together to eradicate these issues from our fixtures. They have no place in football."
Meanwhile, Liverpool manager Jurgen Klopp insists the impending departure of sporting director Julian Ward will not impact their transfer activity.
Ward, who took over from the hugely successful Michael Edwards in the summer, is leaving at the end of the season.
Klopp has not ruled out making a move in January to bolster a squad which has been hit by long-term injuries to forwards Luis Diaz and Diogo Jota.
"It was a surprise when Julian told me. But we work completely normal together until the day that he leaves. Julian is 100% committed and everything is fine," said Klopp.
"We never had a problem and will not have a problem, so it's all fine.
"He told me after the Southampton game (their last game before the World Cup break) and it was a surprise at that moment. That is his decision and that's OK.
"It will have no impact for this period, not at all."
The injuries to Diaz and Jota have been compounded in the short term by the absence of Roberto Firmino, who missed the cup exit to Manchester City on Thursday and is set to be unavailable for the next couple of games.
Liverpool's squad does need bolstering, with midfield an area which has long required some attention, and Klopp has not ruled out another surprise January signing like that of Diaz almost 12 months ago.
"January, in our situation, it's a window where we always say from sport side we are always prepared. That's how it is," he added.
"We always work with what we've got and that hasn't changed. We are looking and if something happens, we will see."
Liverpool are likely to welcome back World Cup stars Alisson Becker, Trent Alexander-Arnold and Virgil van Dijk for the Boxing Day trip to Aston Villa.
Alexander-Arnold sat out the City match through illness, which has affected a couple of players, while Alisson drops out of the League Cup to allow Caoimhin Kelleher to start. Netherlands captain Van Dijk only returned to training this week.
