In support of the defeat in the 2025 Su Cup, the Malaysian national badminton men's doubles coach denied that Xie Su's form had declined

Malaysia's men's doubles coach Pang Wei Shun believes that former world champions Xie Ding Feng/So Wei Yi's defeat in the quarterfinals of the 2025 Xiamen Sudirman Cup was not due to a decline in performance, but mainly due to bad luck.

Peng Weixin said after training in Malaysia on the 6th local time that the new Asian Championships men's doubles champion Xie Dingfeng/Su Weiyi lost to Japan's Takuro Hoki and Yugo Kobayashi (ranked 17th in the world) in the top 8 of the Su Cup in three games 21-12, 20-22, 21-23, resulting in Malaysia finally losing to Japan 2-3 in the group stage, advancing to the top 8 against China as the second in the group stage, and finally losing 0-3.

Peng Weixin pointed out that Xie Su was unlucky at the crucial moment: "The result of the game itself reflects the fierce competition, we won the first game, but lost the next two games by a narrow margin. "For me, the final score was more of a luck factor than because their performance dropped," he said.

According to Peng Weixin, the selection of players is made collectively by the coaching staff. Although libero Wu Shifei and Noi Zuting recently won their bouts against 2021 World Champions Takuro Hoki and Yugo Kobayashi, they opted for Xie Dingfeng and Su Weiyi after considering the "Championship Halo". At the same time, he said that the latest performance of the Xie Su group after intensive training under his supervision has improved, but there is still room for improvement.

Xie Su's attack power in the backfield still needs to be improved. "Now their style of play is different, but the physical strength and attacking power, especially in the backcourt, still need to be improved," Peng said. He said the pair will next compete in the Thailand Super 500, which will be held from May 13 to 18. The pair is still one of the main players in Malaysia, and he believes that as long as the team continues to work hard, they will be able to bounce back strongly and achieve better results in future competitions.
