London district and football club (7)
I believe the answer is:
chelsea
'london district and football club' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for chelsea that I've seen before include "Part of Manhattan" , "Word linking boot and bun" , "The Blues of Stamford Bridge" , "upmarket part of London" , "Cheyne Walk neighbourhood?" .)
