Over the next 25 years clubs sprang up all over the capital, and the majority of these teams are still thriving in the 21st century. Of those clubs currently playing in the Football League, Fulham is generally considered to be London's oldest, having been founded in 1879.[7] However, Isthmian League side Cray Wanderers is the oldest extant club in all of the Greater London area, having been founded in 1860 in St Mary Cray[8] | (then part of Kent but now in the London Borough of Bromley).
