Irrespective of the absence of their regular skipper Bhaichung Bhutia out due to knee ankle injury, Mohun Bagan dominated the final right from the start on a misty and cold evening at the Yuba Bharati Krirangan in Salt Lake stadium.
Having missed a couple of chances and playing goalless in the first-half, Mohun Bagan tried their best after the changeover and PC Lalawmpuia almost scored immediately after the break but only to see his shot going out of target.
In the 67th minute, Lalawmpuia got a golden chance but only to see his shot saved as corner was given in favour of Mohun Bagan. Lal Kamal took the corner which looped into the Dempo box as Habibur Rahman Mondal headed it for Barreto to take the shot.
The Brazilian’s powerful strike hit the cross before going into the Dempo net as the boisterous home crowd began celebration bursting firecrackers.
The Barreto goal also avenged Mohun Bagan’s 0-2 loss to Dempo the last time the two teams met in a Federation Cup final in 2004.
Dempo looked for for an equaliser with the Goans charging up after the conceding the goal but in turn they were reduced to 10-man army with their ace striker Ranty booked twice after the Nigerian brought down Marcos Pereira in the 78th minute.
