Dundee United chairman Stephen Thompson has hit out at the SFA for not issuing more concessionary tickets for the William Hill Scottish Cup final against St Johnstone.
He claims that their pricing policy could leave Celtic Park with 20,000 empty seats on May 17.
The Tangerines contacted the governing body after all of their reduced price tickets for the Lisbon Lions Stand were snapped up on the first day of sale on Monday.
Supporters were keen to get their hands on the £28 adult and £10 concession briefs, leaving only £35 tickets available for the North and Main Stands.
Thompson says that the absence of a concessionary option has slowed up sales after a bumper opening day that saw almost 17,000 purchased.
“We have asked the SFA for more concession tickets but they have said no,” confirmed Thompson.
“As a result of that our ticket sales have slowed dramatically and I think you will be lucky to get 40,000 at the game.
“There could be 20,000 empty seats. Do they want that or would they prefer people to go to the game?
“It is discouraging people from going. There is a huge difference in price between the concessions and the non-concession tickets.
“For two adults and two kids in the concession section it costs £76 but now the SFA want us to sell tickets for £35 each and no concessions for kids, pensioners or students.
“That means for a family of four it’s going to cost £140, which is far too much for a lot of people to afford. It makes no sense to have no concessions in the other sections of the stadium.”
Meanwhile, it has been confirmed that a special train will carry United fans to Glasgow Queen Street.
It will travel via the Forth Bridge due to engineering works near Stirling. There will be further trains added if the demand is there.
