A-League premiers Central Coast kept their unbeaten record at the 2013 Menpora Cup intact with a comfortable 2-0 victory over Malaysia's under-23 side Harimau Muda in Bandung on Sunday.
Goals to Matt Simon, his second of the tournament, and Mitchell Duke made it two from two for the Mariners who are now well positioned to qualify for the final of the eight team international invitational competition.
However, they still have some work to do if they are to make the tournament's showpiece match in Malang.
Group A rival Persib Bandung defeated Sriwijaya FC 2-1 in the fixture immediately following Central Coast's win over Harimau Muda, to ensure they're in with a chance to qualify for the final in the group's last game.
The Mariners need only draw against the popular local club to book their tickets to Malang, however a defeat to Djadjang Nurdjaman's charges would eliminate Arnold's side.
"We totally dominated the game - I don't think (goalkeeper) Liam Reddy had a save to make," coach Graham Arnold said.
"But he swept the backline very well and overall I was quite pleased with the effort."
Kick off between the Mariners and Persib Bandung on Tuesday 24 September is at 6:30pm local time (9:30pm AEST).
Former Hyundai A-League marksman Sergio van Dijk is expected to make his first appearance in the tournament for Persib Bandung against the Mariners.
