Skipper Manpreet Singh, though delighted with the team's exploits against the Olympic Champions, cautioned his teammates about reading too much into the results.
Goals from Harmanpreet Singh (11th minute), Lalit Upadhyay (25th) and Mandeep Singh (58th) on Sunday gave the visitors a deserved triumph over Los Leones.
It was Varun Kumar (7' and 44'), Rajkumar Pal (13') and Rupinder Pal Singh (14') who scored for India, while Leandro Tolini (10'), Lucas Toscani (23'), Ignacio Ortiz (42') and Lucas (57') scored for the home team.
