Street traders at Stamford Bridge have been dismayed to discover Chelsea have declared war on the half-and-half scarf.
The club have won the right to trademark the word 'Chelsea' on all clothing items and will crack down on unofficial merchandise sold outside the ground on match-days.
Traders have been warned they now have just three home matches in which to sell off any existing stock, starting with Monday's derby against West Ham United — Chelsea's opening game of the new Premier League season.
The word 'Chelsea' is now a trademark in Class 25, which covers clothing, replica football kits and headgear, but the London Borough of Hammersmith and Fulham specified the scarves in a letter to stall holders, sent out last week.
