Not too surprised to see Leicester with the biggest support in Leicester.
As for where i'm from (North Hampshire) i'm surprised that Arsenal are top in almost every area, I thought it would be easily Chelsea. Also surprised that Man Utd are only fourth in most places (generally behind Arsenal, Liverpool, Chelsea in that order).
Last surprise was that Southampton have the most following in North-West Hampshire. In the very south (Southampton, Eastleigh) I could understand, but didn't realise their support across the whole county is almost enough to knock the biggest in the league.
I live in Rochester and Strood on that map - I have NEVER seen anyone in an Arsenal shirt/club paraphernalia, flag, badge in a car etc... in either town in the 3 years I have lived here. Obviously they just like to silently follow from twitter. I have however seen loads of Chelsea shirts, flags, badges etc etc... so am surprised they are not top.
My previous place of residence is more like it - Bethnal Green and Bow - Arsenal was the main support you saw day in day out in Whitechapel.
I always find things like this interesting because it shows how the fans of Englands historical top teams take over the map. Other than specific areas like Leicester, Burnley, Southampton, Swansea, Birmingham etc. who support their local teams, and Chelsea who have areas here and there, the whole of the UK is divided between United, Liverpool and Arsenal. And it just shows how unnatural the rise of Chelsea and City has been for the Premiership. Just shows how weird the unnatural rise of those teams has been.
In an outwardly supporting mode on da streets and all that it's Chelsea, although thinking about it those people who I constantly see in Chelsea tracksuits/shirts etc... most likely don't have computers and if they do would have no idea how to even spell twitter, let alone use it.
