Jakarta: Philippines' James Younghusband knows how the atmosphere inside the Gelora Bung Karno Stadium can intimidate visiting teams.

And as the Azkals aim for a semifinal berth against an already-eliminated Indonesian side on Sunday night in their final Group B match, the veteran midfielder believes confidence stemming from past performances will serve them in good stead in the face of the hostile crowd and the home team raring to play the spoiler's role.

The Azkals only need a draw to advance to the semifinals, but a defeat coupled by a Singapore win over Thailand in Bangkok will eliminate the Filipinos. 

“We’re looking forward to the challenge,” said Younghusband. “Our team is very positive and relaxed. It’s all about confidence right now and I think our previous matches in the competition have given us that.” 

The Philippines are second in Group B, having won two matches against Singapore (1-0) and Timor Leste (3-2), before holding Thailand to a 1-1 draw at home. 

But facing Indonesia for the final match in the group stage is a tough task as the Merah Putih enjoy tremendous support at the 68,000-seater GBK. 

Younghusband was part of the Philippines team that played both legs of its first-ever semifinals appearance at GBK eight years ago against Indonesia. The Azkals lost, 2-0, on aggregate, but the experience remains one of the highlights of members of that 2010 squad. 

"I think it was the atmosphere,” said Younghusband, who has 97 caps. 

"We couldn’t really talk to each other. It was so loud. The whistles and the horns. Those are the moments you dream of when you’re a really young kid. We’re thankful we got to experience this.”
