Watford went out of the Carabo Cup at the third round after Javi Gracia’s men lost on penalties to Tottenham Hotspur at Stadium MK.
Isaac Success put the Hornets ahead early in the second half but the Nigerian’s strike spurred Tottenham into life as Mauricio Pochettino’s men began to dominate.
After Adrian Mariappa was lucky not to concede a penalty, it was Dele Alli who equalised from the penalty spot after being brought down by Christian Kabasele who was sent off.
Erik Lamela then put the North London team in front for the first time in the game.
Not to be outdone though, former Spurs player Etienne Capoue took the game to penalties when he hauled Watford level with just seconds left.
Tottenham keeper Paulo Cazzaniga then saved efforts from Capoue and Domingos Quina before former MK Dons favourite Alli sored the winner on the return to his old stomping ground to send Tottenham through to the fourth round.
The game was held at Stadium MK because of delays in the construction of Spurs’ new home.
