Racism in association football fans had sung "The Famine Song" at Celtic Park. "The Famine Song" was also sung in March 2011 at a Scottish football game by Rangers fans, nevertheless, Scottish Justice Secretary Kenny MacAskill described the match as a "great advert for Scottish football". "The Herald" journalist Doug Gillon has written that "the sectarian intolerance which divides Scottish society [...] is rooted in anti-Irish racism". In February 2011, in an Old Firm match at Celtic Park, a Celtic supporter was caught mocking black Rangers player El Hadji Diouf with monkey noises and gestures as he was about to take a corner kick.
