Error-prone East Bengal let slip a two-goal advantage as Odisha completed a stunning second-half comeback to win 4-2 at the Salt Lake Stadium on Friday.
The dramatic and equally frustrating loss keeps Stephen Constantine's side eighth in the Indian Super League table with a mere tally of six points from seven games, while Odisha move up to third with yet another comeback win.
It was surprisingly a one-sided affair in the first-half with East Bengal dominating the proceedings in a high-voltage encounter, with the crowd on their side.
Goals from Thongkhosiem Haokip and Naorem Singhhad put the home side on course to secure confidence-boosting back-to-back wins, with Suhair VP putting on the plate on both occasions and bagging two assists.
But visitors' fightback began when substitute Pedro Martin made instant impact with a quick-fire double inside a minute to level things up at 2-2 early after break.
The away side then scored the third as another substitute Jerry Mawihmingthanga coolly heads home at backpost before tricky Nandhakumar fired in the fourth to silence the home support and put the game to bed.
