United will get just 1,992 tickets for the still-to-be-arranged trip to West Ham, Reds Away can reveal.
The figure was revealed in documents Newham Council made available to Reds Away after a long-running legal battle.
The papers show the council-run safety advisory group (SAG) made the decision on the league game allocation last October.
Minutes from the SAG’s October 10 meeting quoted Lou Elliston, who is the London area’s inspector of the Sports Ground Sports Authority, which advises SAGs on stadium safety.
She said United fans would be in the North Stand lower tier and added: “Gangways must remain clear at all times.”
She said that at the 2010/11 league game ”there was a reduced allocation (from the entitlement of 3,000 to 2,200) and there were still problems.
She added: “Damage was caused on the concourse and a female employee from the catering staff was punched in the face.”
To stop fans blocking the aisles, Ms Elliston confirmed two columns of seats from each block would not be sold.
She added: “It is probable the fans will misbehave and cause serious issues on the concourse and the numbers should be reduced to 2,000.
“The concourse is very narrow and dense.”
Newham Council licensing officer David Grant agreed with her, as did at least one other person at the meeting.
It was confirmed at the February 20 meeting that the precise figure was first thought to be 2,037 but was actually 1,992 once the requested restrictions were apply to the seating plan of the away end.
The minutes do not cover any discussions relating to how the 1,992 figure was arrived at, as the requested restrictions would only remove a few hundred seats from sale, not 1,000..
It is possible the SAG members arrived at this figure as they are confident that they can safely accommodate 1,992 in the concourse area and clampdown on persistent standing.
But there was no specific reference to this.
At a December 14 meeting, Superintendent Craig Haslam said, in reference to the forthcoming FA Cup game between West Ham and United: “No intelligence has been received to suggest that there will be any disorder.”
The documents also reveal that, for the FA Cup game, United got 4,488 ticket – around the amount other sources had said at the time.
West Ham made preparations for United to challenge the decision.
The club’s operations director Ben Illingworth said: “If (United) complain and go to the Football Association, it will come back to the SAG, who will explain that the decision has been made.”
Reds Away editor Dale Haslam said: “Now Newham Council has released these minutes, MUST and others can try to understand some of the safety issues the SAG members have identified.
“If fans do not block aisles and do not overcrowd the concourse then that would demonstrate fans are willing to improve safety in the eyes of the SAG and, in theory, the allocation could be increased.
“The one remaining concern is that the minutes do not detail any in-depth discussion of the safety concerns, which is disappointing given that reds have been denied more than 1,000 tickets.
“It is also disappointing that comments were made at one of the meetings predicting the likely behaviour of our fans based on no evidence whatsoever.”
