An inconsistent India lost 1-3 to Netherlands to slump to their second defeat in the ongoing Hockey World League (HWL) Final and finish at the bottom of Pool B.
"We should get more out of our circle penetrations. One of the things which is hurting us is the final pass. Our final decision needs to improve," a visibly disappointed Oltmans said.
"If you enter the circle at a very high speed and you don't take time to give the final ball to the right player then it's disappointing. If you see how Holland scored the last goal, it was the right final pass and that is one of the things we need to change, especially at the top level."
Netherlands took the lead in the 36th minute through a penalty corner conversion by Mink van der Weerden before Mirco Pruijser (43rd) and Roel Bovendeert (54th) scored two field goals. India's lone goal came from the sticks of Chinglensana Singh in the 47th minute.
Oltmans said after a decent opening half, the Indians lacked in structure and organisation.
"In the third quarter we made mistakes. Our structure and organisation was not up to the mark. We were quite unlucky with the second goal as we were one man short, although I am a bit doubtful about that card (to Rupinder Pal Singh).
"We went all out in the last quarter to see if we could get back into the goal and try to get a draw. We even scored one, but then conceded one," he said.
