Depends where you are scouse central where I am in the midlands.Most of my friends are Leeds fans. There are also large numbers of Arsenal, Chelsea, Spurs, and as it turns out, City fans.
One of my regular fourball is a Luton fan. I know Watford and Coventry fans. West Ham also have a lot of supporters here. While Liverpool may be the best supported, in no way are they a majority of all football fans. It‘s crazy to suggest any different.
