This 100%. Jealousy of each clubs “golden” period.My nieces husband a rag has trained his three year old daughter to shout DIRTY SCOUSERS whenever Liverpool is mentioned. He just has a world weary acceptance of Citys current dominance. As
he is from Fleetwood he doesnt have the same issues with local pride a Manc would have. When the dippers won the title some of their idiots drove round OT shouting abuse at rags. When the rags won the title at Goodison the police had to prevent their fans dancing a conga round Anfield. Foolish to claim their is lack of animosity between the two fan bases. Dont think this goes back that long however based on Uniteds jealousy of Liverpool in the 70s and 80s repaid with interest by the scousers in the 90s and noughties. Our denying Liverpool the title on several occasions has been the one consolation of our success according to rag friends and rellies. No doubt that Liverpool hate us also these days but think they would hate anyone better than them equally.
At first they didnt take City seriously (why would they) but as it now seems were on a relentless march to catch them both up, and in time surpass them. They are doing everything they can to stop us, by whatever means necessary.
They have seen the future and dont like it very much
