Manchester United fans are threatening legal action over the decision to cut their allocation of tickets for the Premier League game at Chelsea a week on Sunday.
United expressed their disappointment last week after confirming that the number of away tickets for the game at Stamford Bridge on October 22 has been slashed by more than 600 due to policing concerns.
The club had already sold their allocation of 2,994, but the Metropolitan Police sought to reduce that to 1,500 before a compromise of 2,370 was agreed after United appealed to the local Safety Advisory Group.
