Hampton School first team coach Carlos Mills hailed his Independent Schools FA U18s Cup winners after Thursday night's emotional triumph over Millfield School.
Goals from Charlie Gerson and Dec Ryan secured a 2-1 win in front of more than 600 fans at League One MK Dons' Stadium MK to complete a historic cup double for the school.
Hampton's U15s team had lifted the ISFA U15s Cup for the first time seven days earlier after penalty shoot-out triumph over Bolton School at League Two Burton Albion's Pirelli Stadium.
"We went into this game with a lot of confidence and self belief," said head of games Mills.
"As expected, Millfield put us under lots of pressure especially early on in the game. We adapted accordingly to counter this and our resilience and determination paid off.
"All season the first XI have excelled and, in an emotional evening, it was great for all to see their hard work come to fruition with such a tremendous victory."
