The Red Devils' 4-0 win over Wigan was marred by the chants emanating from a small number of home supporters, following on from this week's damning report on the handling of the Hillsborough disaster in 1989 in which 96 people died.
The report laid bare a shocking cover-up that attempted to shift the blame for the tragedy on to its victims.
But despite manager Alex Ferguson's pre-match plea for supporters not to sing songs about the disaster, one clearly audible chant during the match at Old Trafford was "Always the victims, never your fault."
Speaking after the match, Manchester United Supporters Trust chief executive Duncan Drasdo echoed Ferguson's sentiments.
He said: "We agree 100 per cent with the statement made by Sir Alex Ferguson - this is the time for supporters of these two great clubs to represent their clubs with the integrity and honour that our glorious history demands."
