HAYES & Yeading need another £2million to complete the stand at their new stadium.
United must raise that staggering sum to get the Beaconsfield Road venue's new main stand finished and enable the ground to meet the National Ground Grading Category B standard.
The club are currently fulfilling home fixtures at Woking’s Kingfield Stadium in Surrey and have an arrangement to play there for the whole season if necessary.
New United chairman Tony O’Driscoll last week revised his Christmas target for having the Sharda Glass Community Stadium ready for action after discovering problems that have stopped work on the site.
No progress has been made in recent weeks, and O’Driscoll – who has previously held the positions of manager and director of football at Hayes & Yeading – is striving to solve the issues.
An ongoing dispute with the builders over payment and a shortfall in funds needed to complete the work has left the United chief facing a massive challenge.
O’Driscoll told the Gazette: “I’m learning things every day. It depends on how bad things are and where we are with this as to how long I can go on for.
“The builders are saying that there’s another £2million of work on the stand to get it finished, but we don’t have £2million so we need to see how much we can get done with the money we have got and see where we are then.
“The builders have pulled off and said that we owe them money.”
MC Contracting, which has the building contract at Beaconsfield Road, was approached for comment by the Gazette but did not want to make a statement.
Sharda Glass, the Hayes-based glazing firm which signed a two-and-a-half-year naming deal for the new stadium in December 2012, also declined to comment.
Meanwhile, it was a mixed bank holiday weekend for United on the field as they produced a sensational display to beat Boreham Wood 3-1 on Saturday and then slipped to a narrow 1-0 loss to leaders Eastbourne on Monday.
