Another youthful Leeds side were losing 3-0 before a tactical change from coach Steve Agnew saw him put Milner in central midfield and the teenage star began to run the home defence ragged.
Kettering went into the lead with two goals against the run of play for Matt Murphy and another from young striker Brian Hardie to leave United on the brink, then enter the teenage prodigy!
It left Steve Agnew ecstatic with his performance, and hopefully has given Peter Reid another option to consider.
Milner showed why he is considered to be a potential star of the modern game, seizing on a mistake from keeper Paul Pettinger to finish from outside the box before shaking off two defenders with his quick feet and slotting into the bottom corner for his second of the game.
Then, with the game as good as over, a slip from the otherwise immaculate Brett Solkhon let Milner in for a one-on-one which the 17-year-old smashed home.
