It took an own goal from Pakistan captain Samar Ishaq in the 14th minute that ensured three points for Sunil Chhetri and Co. The Indian will take on Bangladesh in their second group league encounter on Tuesday.
The match was billed as a contest between Pakistan defender and former Fulham player Zesh Rahman against Chhetri. Both disappointed during the 90 minutes of play. While 30 plus Rahman has become slow, Chhetri's profligacy in the 18-yard box cost India three clear chances.
The winner in the 14th minute was more about a defensive error on the part of Pakistan.
Right wing back Nirmal Chhetri overlapped and tried to find an onrushing Sunil between the two rival stoppers in the opposition box but Pakistan captain Samar in his bid to keep his Indian counterpart at bay made a faulty clearance that entered his own goal.

India's best player on the day was young right winger Francis Fernandes who repeatedly beat opposition left half Kamran Khan who was ultimately replaced in the 33rd minute.
Just after kick-off, India were rewarded with four flag-kicks in the first four minutes itself. But Pakistan re-grouped after substitute Saddam Hussain replaced Kamran but the Indian defence stood tall.
Immediately after change of ends, forward Jeje Lalpekhlua barged in from nowhere trying to nod home a Mehtab free-kick down the right but it was just off the mark.
