Leyton Orient were crowned champions of the League 1 Kids Cup after a 1-0 success against Notts County at Wembley Stadium.
Represented by Chase Lane Primary School, the O's sealed the win against Notts County representatives Nottingham School thanks to a solitary strike from Demaray Anyadike.
A national six-a-side competition for children aged 11 and under, the road to Wembley in The Football League Kids Cup started at the beginning of September.
Chase Lane Primary School and Nottingham School battled through a number of local rounds and regional tournaments against other schools to reach the competition's climax, which was staged under the famous Wembley arch prior to the Sky Bet League 1 Play-Off Final.
Tyrone Hercules, the teacher who accompanied the youngsters to Wembley, said: "It's fantastic to see smiles on everybody's faces. The boys did fantastically well. All of those early starts to train them have been more than worth it.
"We've had tournament after tournament and throughout the players were asking how they could get to Wembley - they were determined to do it.
"It has taken a bit of a luck but a lot of skill, and they're now here and enjoying the day. Whatever medal we went home with we'd be happy but to win it was just a lump-in-the-throat moment."
The 14-minute match started at a frantic pace with both sides looking to take the early initiative, but the respective defences began superbly.
Yousef Abu-Mraheel and Rohan Acharya were holding a firm back line for Notts County, while Leyton Orient's Jack Moore and Luke May-Parrott were dealing with everything that came their way at the other end.
It was defender May-Parrott who had the first telling shot on goal; the youngster attempted a long-range, looping effort that was saved well by County stopper Thomas Picker.
Dotun Ogunbayo in the Orient goal also had some work to do, sweeping up a through-ball that the Magpies' Zehn Rana tried to latch on to.
Back came Orient and Picker was called into action again, this time denying the lively Anyadike after the O's attacker had produced a sharp turn and shot.
That left the score goalless at half-time, but you could sense the deadlock was going to be broken as more openings started to emerge in the second period.
For the Magpies, captain Samuel King created space down the right but couldn't find a team-mate in the box, while Acharya slid in to dispossess Harvey Livings-Corbin just before he managed to get a shot away.
Then came the pivotal moment when a hopeful long ball was knocked up field. Magpies 'keeper Picker looked odds-on to get it but, as he rushed out, Anyadike used his blistering pace to nip in and knock the ball past him and into the empty net.
After that goal the youngster gained confidence and his trickery saw him set-up a golden chance for his team to double their lead, but Jayden Bennett failed to convert a low cross.
County tried desperately to find an equaliser and so nearly got it with the last kick of the game but Oliver Brenchley blazed over the bar after good work again from King down the right.
It was a monumental effort from the Magpies and they were extremely unlucky to not find a leveller, but it was Leyton Orient's day.
The team from Chase Lane Primary School lifted the League 1 Kids Cup with the roaring support of the Orient faithful in the West side of Wembley Stadium.
After lifting the trophy, match-winner Anyadike said: "It was so good to play at Wembley - I enjoyed it a lot. The fans were loud and we played well. I was proud of myself to score the winning goal and proud of the team to get this far as it's a once-in-a-lifetime opportunity."
