Who do you think it is Chavski have not been included as they dont have many fans UTD have been included as they always have fans travel up from London, so we are told
Liverpool and United fans make up the majority in all Cities. Mostly Glory hunters. The Chavs havn't reached the heights to gain such followings. - But I expect the Chav and C££Y babies are being born as we speak.
But you still need a certain bit of charm. Neither city or chelski have that. Neither will ever have a wider appeal imo.
Define "Top". At the moment they're doing pretty well and even the "Sack Sam" brigade have gone quiet (but I'm sure they'll flash up again once 'ammers lose two games in a row). But they've never won the League / Prem title..... blimey, even Charlton have had a higher top league placing in their time than West Ham, and a handful of cup wins (the last more than thirty years ago) isn't that much to shout about..... and with a capacity of only 36-ish thousand, even the modernised Upton Park is a very moderate stadium by modern standards. West Ham don't really have any sort of fanbase outside East London. London's best supported...? Well, it's difficult to take seriously any club that uses a bubble machine to get their fans worked up. As for United and Scousepool's cockney reds, let's ignore them. They're just contemptible and barely worthy of mention. London's best supported (in terms of numbers) would probably be Arsenal.
In the following order: Man U, Liverpool, Arsenal, Chelsea, Spurs, Man C, West Ham. People support clubs that win, are rich and have plenty of exposure.
