Baoringgdao Bodo gave the AIFF boys a 10th minute lead but it was man of the match Subham Ghosh who turned it around for TFA with his double strike in the 44th and 72nd minutes.
Just when they looked to have surrendered, Zuala struck one in the 90+4th minute to take the match into extra time but only to score an own goal in the 100th minute to hand TFA the title at the floodlit Mohun Bagan ground.
The AIFF boys are back to back U-18 I-League champions and also won the Subroto Cup this year.
