The striker made his Football League debut at Rochdale during his loan spell at Leyton Orient seven years ago - 15 January 2011.
Now 24, Harry was 17 when he stepped off the bench in the 73rd minute of a 1-1 draw in League One. How times change - the top four in League One at that time were Brighton, Huddersfield, Southampton and Bournemouth.
Harry came off the bench again on Sunday, this time in an FA Cup fourth round tie, to make his 200th appearance for Spurs in all competitions.
Harry scored from the spot late in the game to make it 2-1 only for Dale to snatch an injury time equaliser and set up a replay at Wembley next week.
