Dundee United believe there is still enough time for the Scottish Football Association to change the venue of their cup semi-final against Rangers on April 12.
The match is scheduled for Ibrox Park, the home ground of their opponents, and the Terrors says this puts them at a disadvantage.
United also have concerns regarding ticket allocation and a statement issued by the Tannadice club read: "Our position on the need for a neutral venue remains the same.
"We still hope that the Scottish FA will revisit this as there is still time to do so.
"However, should that not be the case, we urge as many United supporters as possible to attend the tie and get behind the team and counter the lack of neutrality which, amongst other things, exaggerates any ticketing imbalance.
"This imbalance would not be such a factor at a genuinely neutral venue."
United has already been allocated 8,012 tickets, with an option to increase this amount to more than 11 thousand if required.
United's first request for a change of venue was refused by the Scottish FA which selected Ibrox for both semi-finals back in October because Hampden Park is unavailable due to redevelopment work ahead of this year's Commonwealth Games.
Rangers striker Jon Daly, who used to play for United, does not think venue is that important, saying: "I don't see Ibrox being an advantage.
"It is a semi-final, it is a one-off game, it is going to be a great atmosphere and I am sure it will be a fantastic battle between two good sides but I don't see us playing at Ibrox as an advantage."
