"It's a good effort to make the semifinals at the Champions Trophy after the disappointing show at the Olympics," said Nobbs after the 2-3 loss to Pakistan here today.
"A bronze medal would have been wonderful, but we did not do enough today," he added.
Nobbs said the Indian strikers could not match the good work of the defenders.
"Our defence had a remarkable tournament and they did well again today. But our finishing was not good enough. There was a lot of mis-trapping by the forwards and that gave away the chances we managed to create. Those were soft errors, something the boys need to work on," said the Australian.
"Probably some of the mistakes were also due to inexperience, but we have the making of a good side. There are a several good signs for Indian hockey from this tournament," he added.
Nobbs complimented the two deep defenders -- VR Raghunath and Rupinder Pal Singh -- for their compact game, and also young goalkeeper TR Potunuri.
