Hearts begin their William Hill Scottish Cup campaign on Saturday at home to Aberdeen, and head coach Robbie Neilson hopes a full house can inspire his team to victory.
The mouth-watering fourth round Tynecastle clash kicks off at 5.30pm, as second meets third in the tie of the round.
Robbie believes that a packed Tynecastle under the floodlights is as good as having a twelfth man.
Speaking to Hearts News, he said: “We wanted to win against Kilmarnock to set us up for Saturday, but the fans have been great all season, and last season as well.
“It would be fantastic to sell the Aberdeen game out, it would be great.
“The backing that the fans give us at Tynecastle really lifts the team and it would be a great boost to have three stands full of maroon.”
Home end tickets are still available, priced at £20 for adults and £10 for concessions.
Hearts fans can buy tickets – two per account and subject to availability – by calling 0333 043 1874, option 1 then 1, by logging on to Hearts eTickets or by dropping into the Hearts Ticket Centre on McLeod Street.
Meanwhile, it has been announced that should the match finish a draw then the tie will be replayed at Pittodrie on Wednesday 13th January with a 7.45pm kick off.
