The landscape of leadership within the senior Indonesian national football team has undergone a significant transformation ahead of a major regional tournament. Borussia Monchengladbach defender Kevin Diks has been officially entrusted with the captaincy of the Garuda squad by head coach John Herdman for the upcoming FIFA ASEAN Cup 2026. This tactical and leadership shift comes as a necessary adjustment following an unfortunate injury sustained by the team’s regular leader, Jay Idzes.
The announcement was made public by Herdman on Tuesday, September 22, 2026, immediately following the squad’s inaugural training session held at the Madya Stadium in Senayan, Jakarta. Diks, who brings a wealth of European club experience to the international stage, is slated to lead the Red and White contingent as they embark on their campaign to conquer Southeast Asia under the newly structured tournament format.
The Catalyst: Jay Idzes’ Injury and Defensive Shuffling
The ascension of Kevin Diks to the captaincy was forced by circumstances rather than a routine tactical rotation. Jay Idzes, the stalwart central defender who has commanded deep respect and defensive stability for the national team, suffered a setback while on club duty in Italy. Playing for Sassuolo in a high-intensity Serie A fixture against Italian giants Juventus, Idzes sustained a left anterior thigh muscle injury.
Medical evaluations quickly confirmed that the injury would sideline the former captain for an extended recovery period, forcing him to withdraw from the national team roster for the FIFA ASEAN Cup 2026. Idzes’ absence leaves a massive void not only in the defensive line but also in the psychological leadership of the squad, given his vocal presence on the pitch and his status as a unifying figure among both local and diaspora players.
With Idzes unavailable, head coach John Herdman evaluated several candidates within the squad to shoulder the leadership burden. Rizky Ridho, a domestic star who previously wore the captain’s armband during international friendlies against Oman and Mozambik in June 2026, was considered. However, Herdman ultimately opted for the international pedigree and extensive leadership background of Diks to steer the team through the pressures of the regional championship.

Proven Leadership: Kevin Diks’ European Pedigree
Kevin Diks is far from a novice when it comes to shouldering leadership responsibilities on the pitch. The 29-year-old defender possesses a robust resume built on years of high-level competition in top European leagues. Most notably, Diks served as a trusted captain for Danish powerhouse FC Copenhagen between 2021 and 2025. During his tenure in Denmark, he guided the squad through domestic title races and rigorous European campaigns, including matches in the UEFA Champions League.
His transition to the Bundesliga with Borussia Monchengladbach further sharpened his tactical acumen and composure under pressure. When Herdman offered him the armband, Diks accepted the role with a clear sense of duty and humility, acknowledging both the honor of the position and the gravity of replacing Idzes.
"Ya, itu merupakan kehormatan besar bagi saya," Diks remarked regarding his appointment, later expressing his thoughts in English-translated contexts to the broader media. "According to me, previously I have also helped the team a lot, and if Jay is not here, I try to help even more. We miss Jay, but of course, he is not here, so we must take a bigger role. Now I am chosen as the captain, so it is a huge honor for me. I also feel that I can help the team in the future."
Diks’ ability to communicate effectively with a diverse squad—bridging the gap between European-based diaspora players and locally-bred talents—makes him an ideal choice for Herdman’s systemic vision.
Training Ground Intensity and Tactical Preparation
The announcement of the captaincy coincided with the commencement of intensive preparations in the Indonesian capital. Following the arrival of overseas and domestic players, John Herdman led the first official training session at the Madya Stadium on Tuesday, September 22, 2026. Despite the humid weather and the physical toll of recent club matches, the team displayed high morale and sharp tactical focus.
Diks noted that the initial training session exceeded expectations in terms of tempo and execution. "Yes, good. We immediately underwent an intensive and good training session, and in my opinion, today’s training went well," he stated.

Herdman has utilized these closed and open sessions to drill tactical flexibility, emphasizing that the modern demands of the FIFA ASEAN Cup require deep squad rotation. The head coach has repeatedly stressed that this tournament differs significantly from the traditional AFF Championship format of the past, requiring a meticulous approach to player management, physical recovery, and tactical adaptability across a condensed fixture list.
Opening Fixture Against Singapore at SUGBK
Time is of the essence for the Garuda squad as they transition from training grounds to competitive battle. Indonesia’s opening match of the FIFA ASEAN Cup 2026 is rapidly approaching, scheduled for Friday, September 25, 2026. The atmosphere is expected to be electrifying as the team welcomes regional rivals Singapore to the iconic Gelora Bung Karno Main Stadium (SUGBK) in Jakarta.
Playing at home provides a distinct psychological advantage for Indonesia, but it also amplifies the pressure on the newly appointed captain. Diks will bear the responsibility of settling early nerves, organizing a restructured defensive line in the absence of Idzes, and ensuring that Herdman’s tactical instructions are executed flawlessly on the pitch.
Broader Implications and Outlook for the Tournament
The appointment of Kevin Diks as captain marks a new chapter for the Indonesian national team under John Herdman. As the squad navigates the loss of a pivotal leader like Jay Idzes, the ability of Diks to step into the leadership vacuum will be a critical determinant of the team’s campaign success.
With heightened expectations from millions of supporters across the archipelago, the Garuda squad enters the FIFA ASEAN Cup 2026 not merely as participants, but as serious contenders for regional supremacy. Under the seasoned leadership of Diks on the field and the tactical guidance of Herdman on the touchline, Indonesia looks to make a resounding statement starting with their inaugural clash against Singapore on Friday night.
