Although Malaysian Hockey Confederation president Subahan Kamal has hinted at changing the coaching structure, the Dutchman says he is not a person who “runs out of my contract”.

The world No 11 Tigers lost the last chance to secure their ticket after going down 9-3 on aggregate to Britain in a two-match playoff in London over the weekend.

“I and all the parties signed the contract with full brains, because we wanted to achieve something,” said a defiant Oltmans upon arrival at KLIA.

“To get something out of a group in a country is a long-term process, not something you can get overnight.

“We all believe in the potential, but in some areas we have to work harder.

“Nowadays we have social media; everyone can write anything, let them do what they want.”

The 65-year-old, who has tasted World Cup victories as a coach with Holland’s men’s and women’s teams, has a two-year contract until October 2020.

The team had earlier missed a golden chance to qualify for Tokyo 2020 when they lost a penalty shootout to Japan in the 2018 Asian Games final.

The gold medallists qualify automatically as Asian champions.

Malaysia last played at the Olympics in 2000 (Sydney).
