"The team is eager and ready to challenge itself. In the lead up to the Olympics, we have shown some really good performances. It shows the ability of this team against the top sides in the world. Now the idea is to show and prove that it was not one-off," Oltmans said ahead of the team's departure for the Games.
After a 10-day gruelling national camp here, the 16-member Indian team departed for Madrid in the early hours today, where they will play two friendly matches against Spain before heading to Rio.
Newly-appointed captain PR Sreejesh, who replaced long-standing skipper Sardar Singh, was upbeat about his team's prospects in Rio.
"It's heartening to see the kind of support we are getting ahead of the Olympics. This will only motivate us to do better," said Sreejesh, who successfully led the Indian team to a historic silver medal at the recent FIH Champions Trophy.
Sreejesh said in a sporting carnival like the Olympics, they can ill-afford to take any team lightly.
"Every match in Rio will be crucial. Every team will play to win, be it Ireland, Canada or Holland. We can't take anyone lightly. We have our strategy for each team," the experienced goalkeeper concluded.
