Liverpool CEO Billy Hogan says the club will look to hand down bans for any supporter behaving in an unacceptable manner ahead of this week's trip to Manchester City.
And the Reds chief says they remain committed to improving the relationship with City following October's tempestuous meeting between the pair at Anfield.
In a letter signed by both Hogan and his City counterpart, Ferran Soriano, the officials have urged their respective fanbases to show full support in helping rebuild relations in the wake of the two clubs' ill-tempered Premier League meeting two months ago.

Jurgen Klopp's side continue their defence of the League Cup at the Etihad on Thursday night as they play their first competitive match since the 3-1 win over Southampton on November 12.
It will be the first game between Liverpool and City since that 1-0 win for the Reds at Anfield, when the football itself was eclipsed by a handful of ugly incidents that included offensive graffiti about Hillsborough and Heysel being scrawled on to the concourses in the away end.
Senior officials from both City and Liverpool met last month along with members of the newly-established LFC Supporters' Board and their City equivalent, the elected fan network, City Matters, in an effort to ensure any further marring of the football itself is kept to a minimum on December 22.
A joint letter signed by Hogan and Soriano has now been sent to every Liverpool and Man City season ticket holder and match-going member in an effort to calm the tensions.
It reads: "The club has sent the following letter to fans with tickets for the City game on Thursday.
"We write to you today on behalf of both Manchester City FC and Liverpool FC, ahead of our Carabao Cup match at the Etihad Stadium later this week.
"As with any meeting between our clubs, it promises to be a fantastic spectacle of football and we are sure that you are all counting down to kick-off with much anticipation following the break in domestic football for the World Cup.
"The passion and enthusiasm that we see from our fans when we play each other – at the Etihad Stadium or Anfield – is part of what makes matches between our clubs so special, and we know you are committed to creating a stadium environment where everyone is welcomed, accepted and has a fantastic matchday experience.
"Regrettably, based on recent meetings between our clubs, we also know that a minority of fans are responsible for behaviours and actions that have no place in our game.
"We are therefore writing to ask for your full support in tackling these behaviours and to ensure that both of our Clubs’ good names are preserved. You can help us by reporting any incidents via the options at the bottom of this email so they can be investigated.
"We appreciate that some fans may not be aware of the impact of their behaviours on other fans, both inside and outside the stadium, and we will continue to work with our fans on this education.
"It is however important for everyone to be aware that we are fully committed to dealing with unacceptable behaviours and will take action by issuing bans to those found to be responsible.
"We have engaged the Chairs from both our respective fan groups in our discussions and have their full backing to help create the right environment for our matches.
"If we all stand together to report the behaviours and actions that cause harm - including inappropriate gestures, chanting, throwing of objects, as well as any and all forms of discrimination - then we can all concentrate on supporting our teams.
"Thank you for taking the time to read this email, and for your commitment to help eliminate unacceptable behaviours in football.
"We hope you enjoy the match."
City's supporters were also accused of singing songs about the Hillsborough disaster which claimed the lives of 97 Liverpool fans in their most recent meeting, while the visitors later alleged their team bus was subjected to missiles being thrown at it as it left the stadium after Mohamed Salah's goal had won it for Klopp's side.
That game was the third time in six months that City's followers had stood accused of mocking the deaths of Liverpool fans in the Leppings Lane of Hillsborough in 1989, following on from games at the Etihad and Wembley, which were both in April of this year.
Liverpool supporters were also accused of throwing coins at Pep Guardiola during the game with the club releasing a strong statement at full-time confirming the opening of an investigation into those claims. That inquiry was closed at the start of this month over a lack of evidence.
City, meanwhile, did not publicly comment on any of the allegations or incidents during the ill-tempered afternoon of October 16, opting to stay silent as the fall-out from the match continued well into the following week.
Some Reds fans were privately assured that City officials would be looking into the objections about their followers on the day. In emails seen by the ECHO, City's supporter compliance manager also confirmed in response to complaints that "such vile behaviour" would be "dealt with appropriately" after claiming those who were found to have mocked the deaths at Hillsborough were handed "significant bans" for their acts back in April.
The details of both of those investigations have never been publicly released by Manchester City, however. After last month's meeting, both fan groups have reiterated their commitment to improving relations and eradicating an atmosphere that has privately been described as "toxic" during games between Liverpool and Manchester City.
