Thomas Tuchel has staunchly defended the controversial defensive changes he made during England's World Cup semi‑final loss to Argentina. England entered the match in fine form, leading 1‑0 and standing just five minutes plus stoppage time away from reaching their first World Cup final since 1966. However, two quick goals from Enzo Fernández and Lautaro Martínez turned the encounter on its head after Tuchel switched to a five‑man backline midway through the second period. The German coach, who later sparked further debate with remarks about England's "DNA" following the defeat, admitted that he may have adopted a defensive approach a little too early.
He argued, though, that the cumulative fatigue evident in his squad throughout the tournament, combined with Argentina's relentless and unconventional tactics, forced his hand. "You can try to kill me here. But it's my scar, it's not your scar," Tuchel said in a post‑tournament documentary, emphasizing that the responsibility for the decisions lay solely with him.
"I have to live with it. I'm the one in charge and I take these decisions.
No one is more hurt than me; no one wanted it more. People will keep saying, 'If I had made different substitutions, we would have won.' You just don't know that." The turning point, according to Tuchel, began with a dramatic tackle by Djed Spence that kept England's lead intact. The moment sparked a shift in the coach's mindset.
England had taken the lead through Anthony Gordon and were creating further chances through Declan Rice and Harry Kane. Yet an Argentine counter‑attack saw Giuliano Simeone sprint onto a through ball, forcing Spence to make a desperate sliding challenge. Tuchel reflected on that episode: "We performed well in the first half; it was an even contest with good possession phases. I was pleased and felt we were growing into the game.
From the start of the second half I sensed we were on the back foot. Argentina looked freer, finding better solutions. We scored, we had the next chance straight away, we lost the ball, and then that Spence tackle happened.
It changed something in me and perhaps in the players. Suddenly we were playing as if there were only four minutes left, not thirty. Our execution, the details of our build‑up, our ability to press, to switch sides, to keep the ball and recover mentally and physically – we were lacking all of that." Later, after a spectacular save by Jordan Pickford that denied Nicolas González just before the final water break, Tuchel made his first substitution: he withdrew goal‑scorer Anthony Gordon and introduced defender Ezri Konsa, effectively moving England into a back‑five formation.
Describing Argentina's frantic style, Tuchel said: "They played very, very quickly – I’m sorry for the language – they played 'f*** it' football. They had four strikers, two wingers, the two forwards and Messi. They shifted a No 6 to a No 10, took a centre‑back off and added another midfielder. At points they looked like a 3‑1‑6.
We struggled." He recalled a crucial moment just before the water break when England conceded a huge chance: "I thought, we will not survive. This is waiting for death.
We had no possession, we were not defending properly in our 4‑4‑2. We needed help.
I wanted to give the players something – this is what we do now." Drawing on his previous experience, Tuchel explained why he reverted to a five‑man backline: "Against Norway we finished with a back five, against Mexico we did the same and it worked. Argentina rely heavily on crosses; they have four forwards in the final line. I thought, let’s play a 5‑3‑2, then a 5‑4‑1, to handle the width while keeping three centre‑backs to deal with any aerial balls." The pressure continued to mount. Shortly after the break, Alexis Mac Allister struck the woodwork, and Argentina soon found the net twice, sealing England's fate.
Tuchel believes the emotional and physical toll of the tournament contributed to the collapse. England had endured a dramatic comeback win over DR Congo after trailing for most of the match, then played a man down in the thin air of the Azteca stadium, followed by a grueling extra‑time victory over Norway in the sweltering Miami heat. He summed up the cumulative fatigue: "It just piles up through the tournament – Congo, 70 minutes trailing 1‑0; Mexico at altitude; flying to Miami and playing Norway. We are tired, yet we hung on until the 88th minute." When asked whether he could have opted for attacking substitutions instead, Tuchel responded: "Of course you could.
No one knows what would have happened. We might have lost 2‑1 and people would say, 'Is he crazy? He finished the Norway game with a back five, why didn’t he finish this one the same way?' From what I saw, the level of craziness Argentina brought – change after change – demanded an offensive solution to a defensive problem.
That's the coach's job: you try to help, not act for your ego." He added that a more stable performance, with higher possession percentages, might have allowed him to keep the original structure and make attacking tweaks instead. "That would have been a very difficult road, and it could have tortured you," he concluded. In summary, Tuchel accepts full responsibility for the tactical shift, acknowledging that fatigue, Argentina's relentless aggression, and the unique circumstances of the tournament left him with limited options. The debate over his choices will likely continue, but the German manager remains convinced that his decisions were made in the best interest of the team at that moment.
