Real Kashmir humbled heavyweights Mohun Bagan 2-1 and the giant-killing act, one of many engineered by the debutantes in the ongoing I-League, kept their title hopes alive, here on Sunday.
The win against a profligate Mohun Bagan helped Real Kashmir, the first team from the valley to play in India's top-flight, continue their fairy tale run.
The team's sixth victory was achieved on the back of a brace by Mason Robertson, who struck in the 33rd and 74th minute at the Salt Lake Stadium.
Starting as a defender, Scottish Robertson, who was recruited by his father and coach of the club David Robertson, dominated the game to hand the former champions a second successive defeat.
League winning star winger Sony Norde, who made a comeback after missing four matches due to his leg injury, scored the solitary goal for the home side in the 42nd minute.
"Today's win is because of dedication and hard work of everyone at RKFC. The boys were exceptional and I am sure that the spirit continues as we begin our final uphill task," said Sandeep Chattoo, co-owner of Real Kashmir Football Club (RKFC).
"The RKFC wishes to place on record its great appreciation towards people of Kolkata for the love showered on us," RKFC owners Chattoo said.
The result also avenged their home leg defeat to Mohun Bagan as they moved up the pecking order, going past NEROCA FC to the second place.
The Snow Leopards now have a three-point deficit against leaders Chennai City (24) in the standings as the father-son duo continued to weave magic for the club.
Mohun Bagan slipped to sixth place with 15 points from 11 matches and saw their title hopes virtually go up in smoke.
The visitors also capped a fine outing after their 1-1 draw against East Bengal, extending their unbeaten run to seven matches.
