Manchester United and Liverpool have joined forces to launch an initiative aimed at eradicating tragedy chanting.The exhilarating FA Cup quarter-final between the two most successful clubs in England earlier this month – won 4-3 by United with a late goal in extra time – was marred by incidences of tragedy-related chanting by supporters.With the two rivals set to meet again in the Premier League at Old Trafford on 7 April, the charitable foundations of both clubs have come together to deliver an education programme focused on the impact such conduct can have.
