When Switzerland lost Johan Manzambi to a knee injury before their round-of-16 match against Colombia, Murat Yakin did not try to replace the missing attacker like-for-like. He changed the nature of Switzerland's game.
The Swiss became more cautious, prioritising defensive organisation and counterattacks in a 0-0 draw that they eventually won 4-3 on penalties. Colombia created 15 chances, but Switzerland survived and reached the quarter-finals. (reuters.com)
That is the useful way to judge tactical adjustments at a World Cup. A substitution is not automatically a tactical masterstroke, and a formation change is not automatically intelligent. The question is whether a manager recognised what the match was demanding and altered his team's behaviour accordingly.
By that standard, several coaches stood out at the 2026 World Cup. Some adjusted brilliantly during individual matches. Others changed their teams over the course of the tournament. A few made changes that worked until the opposition found the answer.
Lionel Scaloni kept finding solutions when Argentina's original plan stopped working
Scaloni's strongest quality in 2026 was not a particular formation. It was his willingness to abandon one when circumstances demanded it.
Argentina's run to the final was built around that flexibility. Against England in the semi-final, the defending champions initially had to deal with an aggressive English press and a team trying to disrupt their build-up through central areas. Once England scored, Argentina increased the pressure rather than simply chasing the game with more attackers.
Their possession became increasingly dominant after England went ahead. Coaches' Voice's tactical review records Argentina operating from a 2-2-6 build-up for much of the match, with the structure becoming more fluid as England moved between 4-4-2, 5-3-2 and 5-4-1 defensive shapes. Rodrigo De Paul and Enzo Fernández also became more flexible in midfield, with one able to drift wider and help create passing routes around England's block. (learning.coachesvoice.com)
The result was a 2-1 comeback. Lionel Messi assisted Enzo Fernández's equaliser and Lautaro Martínez's stoppage-time winner. (aljazeera.com)
Scaloni's adjustment was especially effective because it attacked the consequence of England's own change. Once Thomas Tuchel withdrew Anthony Gordon and moved England into a deeper defensive structure, Argentina had more room to circulate possession. The Independent reported that Argentina had prepared for England to introduce pace through players such as Bukayo Saka or Noni Madueke after taking the lead. Instead, England became progressively more defensive. (the-independent.com)
Scaloni responded by stretching that retreat.
That is a stronger tactical adjustment than simply bringing on a striker.
Luis de la Fuente won the final by staying faithful to a system that could change shape
Spain's final against Argentina provides the clearest example of tactical consistency becoming tactical flexibility.
Spain started in a 4-2-3-1, but their attacking structure constantly changed. Mikel Oyarzabal dropped away from the front line, Fabián Ruiz advanced alongside Dani Olmo and Álex Baena rotated inside from the left while Marc Cucurella supplied width. On the opposite side, Pedro Porro stayed slightly deeper to give Lamine Yamal room to attack one-on-one. (learning.coachesvoice.com)
Argentina's compact 4-4-2 made central progression difficult, so Spain repeatedly used rotations to create a spare player or pull defenders away from their preferred positions.
The numbers underline how one-sided the territorial battle became. Spain finished with 65% possession, 20 shots to Argentina's two and 34 attacks into the penalty area to Argentina's seven. (learning.coachesvoice.com)
The adjustment that ultimately mattered came after Argentina's defensive injuries and, later, Enzo Fernández's red card. Spain became increasingly aggressive with runs beyond Argentina's defensive line.
When Argentina switched to a 5-3-1 in extra time, Spain continued attacking the spaces around the new shape. Nico Williams came on and attacked the far post. Ferran Torres, already introduced for Oyarzabal, anticipated the resulting knockdown. Giuliano Simeone could not protect the space in front of him, and Torres scored in the 106th minute.

De la Fuente did not win the final by inventing a radically different Spain. He kept presenting Argentina's defence with slightly different problems until one of them finally broke the block.
Didier Deschamps made France more dangerous by breaking one of his own tournament habits
Deschamps' most significant tactical decision came before the knockout rounds had even begun.
France used four attackers at a major tournament for the first time under Deschamps, a departure from the more conservative balance that had characterised much of his tenure. FIFA noted that the change helped France score 10 goals in the group stage, joint-best in the section, and 20 across the tournament, level with England for the overall competition lead. (fifa.com)
The adjustment was also visible within matches.
Against Senegal, France struggled during the first half to break down their opponents. Deschamps then moved Michael Olise into a central role and put Ousmane Dembélé wider. The change gave Olise greater influence between the lines and helped France turn a difficult match into a 3-1 victory. Olise assisted twice, while Kylian Mbappé scored twice. (lemonde.fr)
The interesting part was that Deschamps did not automatically retreat to a safer midfield-heavy setup when France faced stronger opposition.
Before the semi-final against Spain, the tactical question was whether France would abandon the four-attacker structure against the tournament's strongest possession side. Deschamps kept it, selecting Bradley Barcola on the left rather than adding another midfielder. (sportingnews.com)
France eventually finished fourth after losing the bronze-medal match 6-4 to England, so this was not a perfect campaign. But tactically, Deschamps showed more willingness to alter his established formula than he had in previous major tournaments.
Murat Yakin made the best adjustment forced by circumstances
Yakin's change against Colombia was less glamorous than Argentina's comeback or Spain's positional rotations, but it may have been the purest example of a coach solving the problem actually in front of him.
Manzambi had scored three goals and supplied two assists earlier in Switzerland's campaign. With him unavailable, Yakin did not have an equivalent attacking replacement. Ruben Vargas was also absent, leaving Breel Embolo as the lone major reference point in attack. (reuters.com)
Switzerland therefore reduced the attacking risk in their game and relied more heavily on their defensive organisation.
It worked in one important sense: Colombia had the larger attacking volume but could not turn it into a goal. The match finished 0-0, and Switzerland won the shootout 4-3.
There is a limit to calling this a tactical triumph. Switzerland were eliminated by Belgium in the quarter-finals, so the adjustment did not transform them into a title contender. But Yakin correctly understood that replacing a missing creator with more attacking ambition could simply expose the weaknesses created by the absence.
The best tactical decision is sometimes the one that lowers the ceiling while raising the probability of survival.
Thomas Tuchel showed both sides of tactical adjustment in the same tournament
Tuchel belongs in this discussion because his World Cup demonstrated how thin the line can be between a smart adjustment and an adjustment that gives the opponent exactly what it wants.
Against Norway in the quarter-final, England changed personnel at half-time, with Bukayo Saka and Eberechi Eze entering. England's structure evolved as the match progressed, and later substitutions helped them survive extra time. England ultimately won 2-1 through Jude Bellingham's second goal of the match. (englandfootball.com)
Tuchel also used a late defensive change to protect the lead, bringing on Dan Burn and moving England into a 5-4-1. That decision made practical sense with the game entering its final stages. (englandstats.com)
The semi-final against Argentina was different.
England led 1-0 after Anthony Gordon's goal, but Tuchel removed Gordon for Ezri Konsa in the 72nd minute and moved England into a back five. Reece James was later replaced by Dan Burn, while Declan Rice made way for Nico O'Reilly. (skysports.com)
Argentina then took control of the match. Fernández equalised in the 85th minute, and Lautaro scored the winner in stoppage time.
Tuchel defended the decision afterwards, arguing that Argentina's increased rhythm and risk had pulled England deeper. That defence is reasonable. The criticism is also reasonable. Once England stopped threatening Argentina in transition, the defending champions could commit more players forward without fearing the space behind them. (learning.coachesvoice.com)
That makes Tuchel a useful counterexample. A tactical adjustment can be logically defensible and still be strategically wrong for the match.
The best managers adjusted the problem, not the formation
The 2026 World Cup did not produce one universally superior tactical template.
Spain won the tournament through controlled possession, positional rotations and relentless rest-defence. Argentina reached the final by repeatedly changing the way it attacked and defended depending on the opponent. Switzerland adapted downward when injuries removed key attacking options. France became more aggressive under a manager usually associated with balance and pragmatism.
The common thread was not formation.
It was recognition.
Scaloni recognised that England's retreat gave Argentina the ball and space to circulate it. De la Fuente recognised that Argentina's defensive block could be moved through rotations and repeated changes of reference points. Yakin recognised that Switzerland could not simply reproduce their earlier attacking plan without Manzambi. Deschamps recognised that France had enough attacking quality to make four forwards a strength rather than a liability.
And Tuchel showed the opposite lesson in Atlanta: once a team has established a particular threat, removing that threat can change the entire geometry of a match.
That is ultimately what separates a tactical adjustment from a substitution. The meaningful change is not the name on the team sheet. It is what the opposition is suddenly being asked to solve.
