Sunderland will be backed by a sea of red and white when they face Portsmouth in the Checkatrade Trophy final at Wembley on March 31.
The Black Cats have announced that all their allocated tickets for the highly-anticipated clash have now sold out, meaning that they will have nearly 40,000 fans in attendance at the 'Home of Football'.
Tickets went on sale on Friday to the club’s 24,000 season card holders before entering phase two earlier this week, where supporters with recent history of purchasing home league tickets were given the opportunity to secure a seat for the game.
Following the announcement, managing director Tony Davison said: 'Our upcoming trip to Wembley promises to be a special occasion for everybody at the club.
'The fact tickets have sold out within just a few days tells you all you need to know about our supporters and their loyalty, but it comes as no surprise as they have travelled far and wide throughout the season.
'As a club, we appreciate that any time a fixture sells out, some supporters will be left disappointed, but we will be working hard to ensure that wherever you are in the world, you feel a part of a big day for our football club.'
