Tactical Lessons from the 2025 Club World Cup That Will Shape the Summer

The 2025 FIFA Club World Cup, the first edition under the expanded thirty-two-team format, was held in the United States in June and July. The tournament was a logistical experiment, a commercial gamble, and a tactical laboratory all at once. Many of the players who participated will return to the same stadiums a year later for the national team World Cup, and a number of the tactical patterns that emerged during the club competition look likely to influence the way coaches set up their international squads. This piece focuses on the football itself and on what the club tournament revealed about where the game is heading.

The most obvious development was the further consolidation of the possession-based pressing model associated with Pep Guardiola's Manchester City and its many imitators. Real Madrid, despite winning the trophy, did not look like a possession side. They controlled matches through phases of intense pressing, then dropped into a compact mid-block and counter-attacked through Vinicius and Bellingham. The model worked because the players were technical enough to execute the transitions and physical enough to sustain the defensive structure across ninety minutes in summer heat.

Manchester City, who reached the semi-finals before losing to Real Madrid, played the most recognizable version of the modern possession game. The fullbacks inverted into midfield, the center backs split wide, and the build-up sequences began deep in their own half. Against weaker opposition, the system produced sustained spells of pressure and high-quality chances. Against Real Madrid's high press, City struggled to find the wide options and conceded the goal that decided the match from a Rodrygo counter-attack that began with a turnover in midfield.

Bayern Munich, under the management of Vincent Kompany, demonstrated a different approach. They pressed extremely high, often with seven or eight outfield players in the opposition's defensive third, and they accepted the risk of being exposed on the counter if the press could not be sustained. The football was thrilling to watch and produced a quarter-final win over Palmeiras that was one of the most memorable matches of the tournament. It also produced a semi-final defeat to PSG, who patiently played around the press and capitalized on the spaces that opened behind the Bayern fullbacks.

The South American clubs adapted to the tournament context in interesting ways. Fluminense, who reached the round of sixteen, defended deep and looked to break in transition through the speed of their wide players. Palmeiras played a more conventional possession game that relied on the technical quality of their midfielders. Boca Juniors, in their first appearance in the expanded format, struggled physically against the European sides and exited in the group stage. The takeaways for the South American national teams are mixed: the clubs that adapted best were the ones who accepted that European-style pressing would be the dominant rhythm and prepared their squads accordingly.

Goalkeeper distribution emerged as the most important micro-skill of the tournament. Several matches were decided by sequences that began with the goalkeeper bypassing the first line of the press with a long pass into the channel. Ederson, Alisson and Diogo Costa were the standout performers in this category. Coaches at the national team level have been studying their distribution patterns and have been working with their own goalkeepers to develop similar profiles. The implication for the 2026 World Cup is that goalkeeper choice may matter more than it has in any previous tournament.

The other notable tactical trend was the use of late-game personnel changes to shift the team's shape rather than to make like-for-like substitutions. Carlo Ancelotti was the most prominent practitioner, frequently introducing a more defensive midfielder to allow the team to drop into a 5-4-1 in the final twenty minutes of close matches. The substitution patterns produced criticism in moments when the change looked overly conservative, but the results validated the approach. National team managers, who have access to fewer training sessions and less tactical preparation than their club counterparts, may find the shape-shifting approach difficult to replicate without extensive squad familiarity.

The physical demands of the expanded tournament also raised questions that the national team competition will have to answer. Several star players arrived at their preseason camps in August looking visibly tired, and the long-term effects on injury rates will not be fully understood for months. The 2026 World Cup, played a year after the Club World Cup, will be the first test of how the players have managed the additional load. The squads that arrive with their stars in peak physical condition will have an advantage that may prove decisive in the late knockout rounds.
