It was actually 1889 that Lancashire stopped administering Manchester in terms of those services but that’s besides the point, Manchester was still in Lancashire geographically - officially. Those reforms happened because of the population swell and need to do so. Nobody in 1889 or any time after that, up until 1974, ever stated Manchester was no longer Lancashire.I merely mentioned the police force to show who was running that area. I could have said schools/education authority or similar, ie. fire brigade, bin collection.
Lancashire local government stopped running Manchester in 1853 and the border of Old Trafford/Manchester was created.
Old Trafford has never been in the City of Manchester anyway.
