For all the work Burnley have done to promote diversity, the enduring nature of the challenge they face was visible when stewards at Tottenham observed a 13-year-old fan of the Lancashire club abusing Son Heung-min last December.
The adults accompanying the boy, who did not seem to include his parents, were contrite when Spurs sent in child protection officers to deal with the situation. The boy was given educational orientation sessions with the Kick it Out organisation. But to find bigotry in someone so young was grim.
At least there is hope of altering the warped perspectives of a teenager.
