National coaching director Wong Choong Hann said changes could be made as Malaysia prepare to face traditional foes Indonesia in a highly-anticipated Thomas Cup quarter-final showdown on Friday.

Against Japan, both the pairings of Aaron Chia-Soh Wooi Yik and Goh Sze Fei-Nur Izzuddin were a letdown as they lost in straight games to Takuro Hoki-Yugo Kobayashi and Akira Kogi-Yuta Watanabe respectively.

“We will not make changes to the singles department, but we might tweak the doubles. Indonesia may go for a scratch pairing, so we’ll need to be ready for that,” Wong said.

Against Canada, Wong tinkered in the doubles department by pairing Izzuddin with Soh, while Chia teamed up with Goh as both pairs notched wins.

However, Indonesia are a different proposition compared to the North American nation.

World number one Kevin Sanjaya Sukamuljo-Marcus Fernaldi Gideon will most likely be restored as the first men’s doubles after being rested against Chinese Taipei, while the second men’s doubles could see Mohammad Ahsan teaming with youngster Daniel Marthin.

The first men’s singles will see Lee Zii Jia taking on Anthony Ginting, with the Malaysian seeking a second consecutive win after beating the Indonesian at the Sudirman Cup quarter-finals.

The world number eight was satisfied with his performance after a narrow 21-15, 12-21, 21-23 loss against Kento Momota in a marathon 80-minute battle on Thursday.

“It was disappointing to lose that third game as I had a 20-18 lead. But I’m happy with my overall performance, I feel like I’m playing at a more mature and stable level now,” he said.

Cheam June Wei should face Jonathan Christie in the second singles, while Leong Jun Hao who won against Kenta Nishimoto on Thursday, will most likely be up against Shesar Hiren Rhustavito in the case the score stands at 2-2.

Indonesia will be aiming to overturn the 3-2 Sudirman Cup loss to Malaysia, and they will take plenty of confidence having topped Group A with a perfect record after wins over Thailand, Chinese Taipei and Algeria.

Malaysia meanwhile will need to make swift improvements after suffering a 4-1 loss against Japan in their final Group D match on Thursday.
