I agree both semis should be played further north. 3 NW teams and Stoke is just off the north west.
If you wanna take a swipe at united having "cockney reds" if you look at average attendances at united and city, united always have higher averages at the turnstiles. United have had greater attendances every season since 1947.
After the war when united shared Maine road with city, united had greater attendances at citys own ground.
When United were playing in Division 2 during the 1974-1975 season, they still had the highest average attendance of any club in the country, including Division 1.
City were a more successful club on the pitch than United in the 1970s, yet there was a difference of over 13,000 in our average attendances, with United the best supported club of the decade.
