Manchester City have rejected Liverpool's offer to pay for the damage to their team bus last season.
The Mirror says the Reds were ready to pick up a bill that ran well into five figures after City's vehicle came under attack when their players travelled to Anfield for a Champions League tie last April.
But the Etihad club – who go back to Anfield on October 7 – felt that not enough had been done to prevent supporters from throwing bottles, stones and fireworks at the bus.
This is despite making it clear to the authorities in the weeks leading up to the game that they were worried for the safety of players and coaching staff following threats.
Windows were smashed and the roof of the coach was damaged so badly by exploding fireworks that a replacement vehicle had to be sent to Anfield to take Pep Guardiola's team home after the game.
City decided they did not want Liverpool to pay for repairs after seeing film footage of club stewards directing supporters to an area of the ground where the team coach would be arriving.
Liverpool were subsequently fined £17,500 by UEFA for the incident ahead of a game they won 3-0.
