"London is Red" how? Arsenal and Chelsea are great clubs located in London. Arsenal was founded in 1886, while Chelsea in 1905. That's a 19 years difference. But, Chelsea has the complete trophy cabinet and remains the only club in football history to do so. Arsenal on the other hand, hasn't won most of these titles, the closest the club has come in being runner-ups. So London remains Blue respectfully speaking if facts are taken into account. No shades.
