The recent rice of racism in football, exemplified by the taunts by a group of Bulgarian fans during the match between Bulgaria and England is not something new.
Bulgaria itself were fined by FIFA in 2011 for another similar incident.
A CNN documentary from almost a decade ago, shows the history of racism in football. Much of what happened then is still prevalent now.
The documentary covers, among others, the stories of Clyde Best, football in England, and the steps taken to curb racism in the sport.
Best was a former Bermudian football player, one of the first black players in First Division football in England, scoring 47 goals as a striker for West Ham United between 1968 and 1976.
