Northeast United FC defeated former champions ATK by a solitary goal in an Indian Super League football fixture at the Salt Lake Stadium in Kolkata on Thursday.
The home side, who kicked off the fifth ISL season with a 0-2 loss to Kerala Blasters, were reduced to 10 players in the 32nd minute when Sena Ralte was sent off for a sloppy challenge.
The visitors found the winner through Rowllin Borges from a 89th minute corner by Federico Gallego.
It was the Highlanders' first win from five matches against the Kolkata franchise. The win took the Eelco Schattorie-coached side to the top of the table with four points from two matches.
ATK are yet to get off the blocks and remain at the bottom of the 10 team standings.
NEUFC had last beaten ATK way back in October in the 2016 season.
