The Indonesian training camp focused on set-pieces, and Kluivert continued to worry about "attrition".

Written by Han Bing On June 1, the Indonesian team ended its training camp in Bali and returned to Jakarta to prepare for the life-and-death match with the national football team. During the week-long training camp, although there were injuries and players withdrawing for personal reasons, in the opinion of coach Kluivert, the training camp still achieved its purpose.

This training camp, which lasted longer than the one in March, was a better way to instill his tactical thinking in his players. The team also used high-tech equipment to assist with training, with set-pieces including corners particularly enhanced. Indonesian Football Association President Tohir hopes that the Indonesian team can seize the few scoring opportunities to beat the national football team and try to qualify for the play-offs ahead of schedule, as they did with the previous home defeats against Saudi Arabia and Bahrain.

At the training camp in Bali, Kluivert's biggest concern about attrition continues. In addition to the suspension of the main goalkeeper Pas and local winger Ferdinand, Yokohama Mariners right-back Walsh left the team due to injury; On May 29, another wide runner, Reinders Jr., also withdrew from the training camp on the grounds that he needed to take care of his wife who was about to give birth; The 33-year-old naturalized centre-back Amat missed training due to acute laryngitis, and team doctor Ashar said the Spanish half-back must be well rested; As for the injured naturalized central defender Hilges and full-back Dean James, they continue to recover with the team.

Homegrown players have also been plagued by injuries, with first-time Deva United striker Bagascara scoring eight goals and one assist in 31 games this season, second only to Vickery and Jacob Sayuri. But just four days after Kluivert announced the 32-man training camp, he withdrew due to injury, and the coaching staff could only recruit Bandung's 23-year-old winger Putra to the team. Putra has six goals and three assists in 29 games in the Indonesian league this season, and has been involved in the same number of goals as exiting Bhagascara. Of course, Putra is best known to Indonesian fans for his name: David Beckham.

On the evening of May 25, in the final round of Serie A, the Indonesian naturalized captain Ezes played for Venice could not escape relegation, although he left for Bali for training the next day, but the team's relegation blow still greatly affected his mentality. It is worth mentioning that Ezes will also be distracted by the transfer, Bologna and Inter Milan are interested in him, and he is likely to choose another branch this summer. Pais, the main goalkeeper who played a major league game with FC Dallas on May 28; Full-back Kevin Dicks, who won the Denmark double with Copenhagen in the Denmark Cup final on May 29, was unable to participate in the Bali training camp. The two flew directly to Jakarta and waited to meet up with their teammates.

Fortunately, except for the above-mentioned players who withdrew due to injuries and personal reasons, the Indonesian team's training camp in Bali went smoothly. When training began on May 26, a total of 22 players participated. In order to ensure the confidentiality of the training content, the Indonesian Football Association has set up three layers of security personnel inside and outside the training ground. Indonesian photojournalists, who have been given permission to shoot training content after a rigorous review, can only shoot 15 minutes before training in the stands. In addition to protecting tactical secrets, tight security is also designed to isolate avid Indonesian fans as much as possible to ensure quiet.

The most eye-catching thing about this training camp is the naturalized striker Stryker who plays in the Australian Super League, and his muscles are more developed than before, which means that he has stronger confrontation and running ability. Although he has been almost difficult to play this season, and Brisbane Roar did not renew his contract after the regular season in early May, resulting in him currently out of work, he has not been discouraged and has been receiving additional muscle-building training. Previously, despite his excellent skills at his feet and strong awareness in front of goal, Indonesian fans complained that Stryk was not strong enough because of his thin body and always lost possession in confrontations, but now, he has been nicknamed "El Kekar" (strong man) on Indonesian social media.

In this training camp, Kluivert recruited strikers such as Vickery, the Sayuri brothers, Lilipali and Putra, who are generally faster and have better skills at their feet, which can enrich the team's offensive routines. In addition, they can also actively press in the front court to block the defensive counterattack of the national football team. Kluivert heeded the advice of the media and the Indonesian coach and focused on set-piece tactics, including corners, in Bali. Indonesia's tall naturalized defenders Ezes and Dix and midfielder Haye can all use corner kicks to create a threat in the box. In the first leg in Qingdao, Indonesia took advantage of a free-kick opportunity to score first.

The 35-year-old naturalized veteran Lilipali was selected this time because he has good free-kick skills, and in the 2023/24 Indonesian league, he handed in an astonishing stat of 11 goals and 17 assists. Despite the dip in form this season, it can still be used as a secret weapon in free-kick tactics. In addition, Romeni, who has scored consecutive goals since naturalization, and Stryker, who has significantly improved his confrontation ability, will also benefit from the team's enhanced free-kick tactics in the forward line.

Indonesian media also noted that goalkeeper Odero wore Swivel Vision glasses in training, a wearable training device designed to limit the visual angle and force players to use visual focus to track the trajectory of the ball, helping goalkeepers quickly focus on their training perspective and improve eye-hand coordination. In the match against the national football team, Indonesia's main goalkeeper Pais was suspended, and Odero received a strengthened version of special training, which stimulated his state.

The Indonesian media predicted the starting line-up for the national football team, and given the withdrawal of Walsh and Reinders Jr., coupled with the suspension of Ferdinand, the Indonesian team's attack and defense on the right side need to be changed, and the right-back will choose between Dix, Jacob Sayuri and Mangqualan, Dix is the strongest, but Jacob Sayuri is faster and suitable for playing as a right winger. If Kluivert were to play with a three-centre-back system, he would need wing-backs on the right flank, and Dicks would be the first choice. But he has just finished the club competition and has not participated in the Bali training camp, so he may have problems with his team-mates.
