En route their entry into the final, FC Goa recorded a better goal aggregate of 3-1 after the two semi-final legs.
Having lost the first leg semi-final in Delhi by a solitary goal, Zico's boys came out all guns blazing against Roberto Carlos's out-of-sorts outfit.
Joffre (11th minute), Rafael Coelho (27th minute) knocked the stuffing out of Dynamos in the first half while Dudu Omagbemi's opportunistic strike in the 84th minute was like the final nail in the coffin for Robin Singh and Co.
Goa drew the first blood in the 11th minute when Joffre after receiving a pass from Pronay Halder raced down the wide right, beating left lateral back Robert. With John Arn Riise not in position, he unleashed a left-footer that beat goalkeeper Antonio Doblas to crash into the net.
With 0-2 down, it was always going to be a catch up game for Delhi but with their main player Giovani Dos Santos not in his element and Robin Singh being not fed with goal bound balls, it was a Herculean task for Delhi.
The end came in the 84th minute through a set-piece movement. A ball was floated from left flank with Doblas completely out of position and the defenders standing in one line at the near past. An unmanned Romeo Fernandes from the far post neatly played a pull-back for Nigerian talisman Dudu to stab home.
