TV revenues for the tournament, known until this year as the Tiger Cup, are expected to grow on the back of strong ratings to around US$5 million.
However, overall revenue is expected to be down after Tiger ended its sponsorship.
Seamus O’Brien, founder of World Sport Group, the event organiser, said: “Running the event sponsor-free has allowed another brand to have a clean run at it next year. Our biggest challenge going forward is to create a sustainable model for Southeast Asian football, and emulate the successes of Japan, Korea and the Middle East.”
