Hangeland netted both goals in the 2-0 victory over Birmingham at St Andrews.
“I am very pleased to have scored two goals,” the defender told Stavanger Aftenblad. “That doesn’t happen every day.
“We played a good match and fully deserved the win.”
“We have had a good second half to the season,” he added. “If we do manage to finish in the top 10, it has been a solid display by the side.”
