Both teams failed to create clear-cut chances in the first-half, staying defensively organised. As a result, no shots on target were registered. But it was Goa, who appeared more threatening.
Goa were keen to impose themselves on the Highlanders and came close in the fifth minute. Fernandes played a long diagonal pass from inside his own half to find Mendoza on the flank, but the latter shot straight at keeper Subhasish Chowdhury.
The second half saw Persepolis create a number of chances yet again, but were thwarted on each occasion thanks to some excellent rear-guard action from the FC Goa defence.
SC East Bengal played most part of the second half with 10 men after captain Daniel Fox was sent off in the 56th minute.
Brandon Fernandes had a chance to put his side ahead in the game early on when he was set up by Jorge Ortiz on the left. The midfielder got the ball at the edge of the box and curled at the far post but only to see his attempt miss the top corner.
FC Goa returned the favour just four minutes later when Seriton Fernandes and Alberto Noguera played a quick one-two, before sending the former free on the right flank.
