 The first Old Firm match was won by Celtic and there have been over four hundred matches played to date.The Old Firm rivalry has fuelled many assaults, sometimes leading to deaths, on Old Firm derby days; an activist group that monitors sectarian activity in Glasgow has reported that on Old Firm weekends, admissions to hospital emergency rooms have increased over normal levels and journalist Franklin Foer noted that in the period from 1996 to 2003, eight deaths in Glasgow were directly linked to Old Firm matches, as well as hundreds of assaults.The bitter rivalry with Aberdeen developed following an incident in the 1979 League Cup final when Rangers' Derek Johnstone provoked the fury of the Dons support with what they believed was a blatant dive but which resulted in the dismissal of Aberdeen's Doug Rougvie and a Rangers victory.
