India outplayed arch-rivals Pakistan 4-1 in the men's Hockey World Cup 2010 on a dramatic opening day.
Sandeep Singh banged in two penalty corners to help India record their first win in the last four games against Pakistan before some 19,000 delirious home fans at the Dhyan Chand National Stadium.
Shivendra Singh and Prabjot Singh chipped in with a goal each as India wiped off memories of a 1-7 humiliation at Pakistan's hands in the Asian Games final at the same venue in New Delhi in 1982.
India led 4-0 before Sohail Abbas, the world's only player to score more than 300 international goals, narrowed the margin for Pakistan by converting just one of his six penalty corners.
"We must not fly high and keep our feet on the ground because the next match is against Australia on Tuesday," said India's Spanish coach Jose Brasa.
"We dominated the first half, but were lucky to score two more goals in the second session. I think we did not allow the Pakistanis to settle."
Pakistan's coach Shahid Ali Khan conceded India were the better side.
"It was difficult to come back after being down 3-0," he said. "The Indians played really well. The players are obviously very disappointed, but we must not lose heart.
"We can still do well in the tournament. It's not all over yet."
