Tottenham development chief John McDermott has told Spurs' youngsters to savour the moment as they prepare to step into a new era at Tottenham Hotspur Stadium.
Spurs are hoping to open their new 62,000-seater stadium against Crystal Palace on April 3, but need to get through two test events in order to receive the relevant safety certificates from Haringey Council.
The first one will see their Under-18s side take on Southampton in front of 30,000 people, with the second coming next Saturday when a Legends team take on Inter Milan.
All being well their first competitive game will then be against Palace four days later in a rearranged Premier League match.
Tottenham's U-18s will be managed on Sunday by former Spurs midfielder Ryan Mason and McDermott, the club’s head of player coaching and development.
McDermott has previewed the game, telling Tottenham's website: "We trained this morning and now the boys have come down to see the bowl and pitch.
"To come here and see this now, it's unbelievable. The colours, the space, the feel.
"It's going to be absolutely brilliant for these young players to be able to come here to see this and have the honour and privilege of being the first players to play here. It's indescribable really."
While the match is a test event for the stadium itself, it remains a competitive fixture for Spurs' U18s as they battle Arsenal for the title.
McDermott added: "It's a fantastic opportunity for some of the boys to play on the biggest stage of their lives.
"Obviously there are other things as well around making sure everything functions and works here, and that the operations goes well, but for us, the in-depth concentration is around playing well against Southampton.
"I just can't wait!"
