Cong An Hanoi: The Silent Revolution from Unnoticed Runs

Hanoi, late 2026-2026 season – Tuesday's training session at Cong An Hanoi lasted 20 minutes longer than usual. No one in the stands, only bird songs and the sound of the ball hitting the grass. I stood at the corner of the pitch, observing a small detail: left-back Van Thanh constantly adjusted his distance with center-back Bui Tien Dung after each failed press. That was not a technical mistake – it was a signal of a change in defensive system from man-marking to zonal marking, a tactical revolution happening in silence. The biggest changes often start from an unnoticed run. Cong An Hanoi, the 2026 V-League champions, are going through a difficult transition. After head coach Polking left due to poor results, assistant Nguyen Tuan Anh took over temporarily. The last three matches: one win, one draw, one loss – average results, but I saw something different through tracking data. Their PPDA dropped from 12.4 to 9.8, meaning they pressed higher, yet their pass completion rate in the opponent's third increased by 7%. They are learning to control the ball when losing it, rather than just counter-attacking. I remember the day the stadium was so silent you could hear birds singing in the stands. That was the 1-1 draw with Becamex Binh Duong, when Cong An trailed until the 85th minute. I didn't ask questions, I just watched how they stood, how they signaled, and how the match changed course. When the ball went out of play, captain Nguyen Quang Hai didn't shout, he simply changed the way he planted his foot – from a ready-to-pass-short stance to a ready-to-run-forward stance. That was a signal for the whole team to switch to a 4-2-4 attacking formation. Result: an equalizer by Hendrio in the 89th minute, originating from an overlap between Van Thanh and Quang Hai. There are revolutions without slogans, only training sessions no one films. Under Polking, Cong An Hanoi played defensive counter-attack with 5-3-2. But since Nguyen Tuan Anh took over, he quietly shifted to 4-3-3, pushing Van Thanh to attacking full-back instead of deep-lying center-back. His crossing numbers doubled, and Geovane – the center forward – benefited. In the last three games, Geovane scored three goals, all from one-on-one finishes after crosses from the left flank. But ironically, the media only talks about Geovane's form, no one mentions Van Thanh's position change. I write this article to fix that blind spot. I've been on the sidelines for 8 years, I know the league table doesn't tell the whole story. Cong An Hanoi is currently 4th, 5 points behind the top. But their xG (expected goals) in the last three matches is 5.8, while they only scored 4 – meaning poor finishing, but good chance creation. If they improve finishing, they can climb to top 2. However, the downside is the defense: lower PPDA means higher pressing, but when the press fails, they are vulnerable to counter-attacks. The 2-3 loss to Hai Phong came from two goals conceded in three minutes after losing the ball in their own third. That's the risk of the new system. The groundskeepers – the logistics team of Cong An – still care for the grass on the empty field, because they know one day the lights will come back on. I met Mr. Tuan, who has maintained the Hang Day stadium grass for 12 years. "I see the young players running more, running faster. The grass gets kicked up more, but that's a good sign," he said. A coach's hand gesture can explain more than a press conference. In the match against Viettel, I saw Nguyen Tuan Anh raise his left hand 4 times, his right hand 2 times – signals to adjust the defensive midfielder's position. Result: Cong An controlled 54% possession and won 2-0. The biggest signal I get from these training sessions is patience. They are not rushing, they don't need media hype. They just need a few more matches to fine-tune. If I were a fan, I would buy tickets for their upcoming matches – especially against HAGL and Thanh Hoa. Two opponents who like to counter-attack, which will test their high-pressing ability. I ask: will this silent revolution bring them back to the top? Only time and those unnoticed runs will answer.
