Two years ago, Hariss went out on loan from Johor Darul Ta'zim to Singaporean club side Home United where coincidentally Aidil was coaching, the two meeting in the final match of the M-League season this year when they take to the field at Bukit Jalil National Stadium for the Malaysia Cup final.
Then they worked together to help Home reach the 2017 AFC Cup zonal final where they were eventually beaten by Philippines' Ceres-Negros FC. But a friendship was built then that still stands to this day, even though for at least 90 minutes on Saturday, that will put to one side as they try to outdo each other.
