India coach Micheal Nobbs said "silly errors" in the second half of the match cost his side full three points against Japan at the inaugural Asian Champions Trophy hockey tournament.

After the impressive 5-0 win over China, India conceded last-minute goal to draw 1-1 with Japan in their second match of the tournament.

"They (Japan) were playing well in the second half. But we made some silly errors in the end and we paid for it," a visibly disappointed Nobbs said after the match.

The Australian also rued Indian player’s poor fitness levels, saying the Japanese were by far the fitter side on the ground.

"We have to be fit to be able to play against much stronger sides," he said.

 "It's not that we didn't play well. We could have won the match easily if those chances had gone in. But I don't want to delve on lost chances. In the last few minutes, Japan pressed hard and fitness let us down," Nobbs added.     

Full back Rupinder Pal Singh was shown the yellow card around the 50th minute mark, which reduced India to 10 men and Nobbs said it was a turning point in the match.

"We sort of lost our composure there and Japan turned on the pressure. Those are the things we need to learn," he insisted.

Against Japan, India also wasted their first two penalty corners as Ravi Pal failed to stop the push and it proved expensive in the end.
