Chandika Hathurusingha said he would remain Sri Lanka's coach despite pressure to step down from the post.
Local media reported Monday that Sri Lanka sports minister Harin Fernando was not satisfied with Hathurusingha's performance and that he would be asked to resign from the role.
But Hathurusingha, while speaking to the reporters on landing back in Colombo, said that he had expected a better show from the team and would like to complete his tenure.
"I have another 16 months," Hathurusingha said. "I hope to remain until my contract runs out."
Asked if he accepted responsibility for Sri Lanka’s below-par show in the World Cup, Hathurusingha said the entire team management should accept the responsibility.
"All of us must accept responsibility for what happened. I think we expected better performance... We have to think. We must learn from this and move forward. I think I have done to the best of my ability."
A top cricket official said the board was thinking to make changes in the coaching set-up within three months.
"We are looking at a three-month period to complete the changes," said the official, who asked to be unnamed.
"If the head coach refuses to step down, we can't force him out, but we can appoint another above him," Fernando was quoted as saying in the mass-circulation Lankadeepa daily.
The Sri Lanka cricket was in trouble when Hathurusingha was given charges in December 2017.
He was appointed after a successful stint with Bangladesh, during which he guided them to Test wins over Australia and England.
