Liverpool have gone to the Premier League to challenge the decision to reduce their away allocation for next month's fixture at the Etihad Stadium.
The two fixtures between Manchester City and Liverpool this season have been marred by crowd trouble, despite both clubs appealing for good behaviour from fans in December. The Premier League fixture at Anfield saw Liverpool allege that offensive graffiti was left in the away section, as well as offensive chanting about the Hillsborough disaster heard.
City said objects were thrown at Pep Guardiola in his technical area, and that their team bus was attacked on the way home from Anfield. For December's Carabao Cup game, a teenage City fan was injured after a plastic cup loaded with coins was thrown from the away supporters housed in the upper tier of the South Stand at the Etihad.
