The 2026 FIFA World Cup presents coaches, players and practitioners with one of the most complex and challenging performance environments in the history of international soccer, and perhaps in the history of sport. Firstly, the competition has increased in size by 50%, with the new format now encompassing 48 teams in contrast to the previous World Cup’s 32. This expansion has increased both the duration of the tournament, which will now last for 39 days compared to 32 days in 2014 and 2018, and the total number of games played, which have increased from 64 to 104. Teams reaching the semi-final stage are now required to play 8 games compared to 7 previously.
Secondly, the fact that the tournament is to be held in 16 host cities across 3 different countries creates extreme variations in climate, altitude and time zones, as well as significantly increasing travel demands.
But perhaps the most immediate challenge comes from the players themselves, who are reporting to their national team camps having come from vastly different club environments. Throughout the domestic season, players competing for different clubs will have experienced various highs and lows and been exposed to radically different performance models, which in turn will have created varying workloads, fatigue accumulation, mental strains, injury incidence and load management strategies. No two players will arrive at the World Cup in the same condition, therefore every player in each squad will be entering into the tournament at a different level of readiness. For national teams, success may well depend on their ability to mitigate these challenges by integrating data in order to make accurate, informed decisions in the months leading up to the World Cup, during the pre-tournament preparation period, and throughout the competition itself.
In this two-part series, we are going to examine the multifaceted challenges facing practitioners before and during the 2026 World Cup, and discuss why an Athlete Management System (AMS) such as Apollo might not just be useful, but essential. Here in Part 1 we take a look at the issues confronting national teams both in the weeks leading up to the World Cup, when players are still with their parent clubs, and in the immediate pre-tournament preparation period when national team squads have assembled for their training camps.
Challenge 1:
Establishing Player Readiness
Professional soccer at the highest level is constantly changing. Evolving tactics have increased the physical and psychological demands being made upon players, with long term analysis of physical output data repeatedly demonstrating that the high intensity components of the game have become significantly greater. In addition to this, playing schedules have become increasingly congested, with expanded competition formats such as the Champions League and the World Club Cup meaning that the best players in the world are required to play ever more competitive matches.
This issue is highlighted when we look at the final week of the domestic schedule. The final matchday at club level for players named in World Cup squads is May 24th, meaning that clubs must release players to their respective national teams by May 25th. International training camps are held in the first week of June, with many countries scheduling two friendly matches during this period before the tournament proper gets under way on June 11th. However, continental club competitions such as the Champions League extend beyond the release date, with the final of that competition held on May 30th. This means that, for these players at least, World Cup preparation time will be severely limited.
For national teams, this problem is then compounded by the fact that no two players will arrive into training camp in the same physical or mental condition. Some may have played over 50 matches in the preceding domestic season, whereas others may have played a peripheral role for their clubs or be returning from injury. Some may be match-fit but fatigued, whilst others may be fresh but underloaded. Crucially, some players will be riding a wave of euphoria having ended their season by winning a major trophy, whereas others will be despondent because they missed out. As a consequence of this, national team players will be reporting into camp having been exposed to different levels of sustained physical and psychological demands across a long club season. By the time they report for World Cup duty, each player within the squad will be highly likely to be experiencing very different levels of neuromuscular, structural, metabolic, psychological and emotional fatigue.
This presents national team performance staff with a unique challenge: namely, how can they establish the current performance status of their players? Without clear visibility into each player’s true physical and mental condition, national teams risk applying uniform training loads to a highly non-uniform squad of players, with each one at a different level of preparedness. A session that serves as effective maintenance for one player may represent a dangerous spike in load for another, risking maladaptation and injury. This makes the transition period from club to international soccer a high-risk period.
One of the ways that Apollo addresses this is by creating a centralized, real-time readiness profile for every player. By integrating club-derived load data, medical history, match exposure, subjective wellness inputs and travel & recovery metrics, national team staff can make data-informed decisions prior to players reporting into camp. Historically, a major sticking point for national teams to gain access to this data was that it had to be collated and transferred manually by club staff, who, due to their considerable work burdens, would not regard it as being a high priority task. As a result player data transfer was often delayed, sporadic and fragmented, if it ever arrived at all. However, Apollo works around this by communicating directly and securely with the host club’s database, automatically transferring relevant player data directly onto the national team platform and translating it into a reporting format that is specific to the requirements of the national team staff.
By centralizing all relevant data, Apollo allows national team staff to segment players by readiness profile, enabling them to adjust training loads dynamically and maintain a unified tactical plan whilst at the same time individualizing physical preparation. The result is a smoother transition phase, reducing the risk of maladaptation and providing a stronger foundation for tournament performance.
Challenge 2:
The Most Important Ability is Availability
In tournament soccer, availability is everything, with evidence supporting the view that the most successful teams are the ones who keep their best performers available for the longest amount of time. Coaches with greater player availability have more strategic options, which improves team effectiveness and positively influences the results of games. World Cup history is littered with stories of star players who, having sustained injuries at the worst possible times of the season were then in a race to be fit for the biggest tournament in their career, only to subsequently break down or underperform in the opening games. Teams win tournaments when players are fit, fresh, and consistently available across multiple matches, and losing even one key player in the early stages can change the trajectory of the World Cup.
For this reason, a fundamental part of the Apollo philosophy is that player availability should not be regarded as a simple medical outcome, but instead should be viewed as being a strategic performance asset which is shaped by training decisions, recovery strategies, environmental exposure, and alignment across different staff groups. To achieve this, Apollo integrates multiple factors which are known to contribute to increased player availability, such as injury history, GPS outputs, training load, recovery markers, individual wellness, environmental exposure, game minutes and so on, and combines them all into a powerful coach’s report that is both insightful and easy to understand. Through this report, Apollo empowers teams to identify not just who is available today, but who is at risk for tomorrow. This shift from reactive to proactive management is a critical factor for success in short tournament cycles.
Challenge 3:
Freshness Over Fitness
One of the key differences between club and national team preparation is that national team practitioners are not trying to build fitness, they are trying to maintain it. When players arrive into the pre-tournament camp from club environments, they already possess high levels of physical capacity which they have built throughout the domestic season. Therefore, the goal is not to overload them, but to reduce fatigue so that they can express that capacity during competitive games. In tournament environments such as the World Cup, more training is not necessarily better, and this is the moment where tapering and load management become critical. Key physical qualities including maximal sprints, high speed running and the ability to perform high intensity technical skill actions throughout the entire game can all be maintained by exposing players to their ‘minimal effective dose’, a tapering strategy which is created by reducing training volume whilst maintaining high levels of relative intensity.
Crucially, this is not a one-size-fits-all process. Players who have accumulated high match minutes typically benefit from significant reductions in training load, allowing fatigue to dissipate. In contrast, players with limited recent game exposure may require targeted reintroduction to high-speed running and match-specific demands to minimize detraining. The challenge for national teams is to manage these contrasting needs within a unified training environment. Apollo enables practitioners to create this specific training environment by tracking player exposure to high-intensity actions whilst monitoring neuromuscular load, thereby ensuring that players are receive enough of a training stimulus to maintain performance whilst not adding to the fatigue burden.
By carefully observing and recording cumulative load and fatigue, practitioners can apply specific task constraints and modifications into their training sessions which can accommodate all players. This then allows training volumes to be individualized and adjusted whilst intensity is maintained, all within a unified training environment. This level of individualization enables teams to preserve freshness, reduce injury risk and increase the likelihood of maintaining high performance levels throughout the entire World Cup.
To Be Continued…
The usual challenges associated with preparing players for tournament soccer are further amplified by the unique demands of the 2026 World Cup. The expanded format increases the number of matches and extends the duration of the competition, while the multi-country hosting introduces significant travel requirements and exposure to a wide range of environmental conditions. Teams may encounter heat, humidity, and altitude within a single phase of the tournament, often with limited recovery time between matches. In Part 2 of this series, we will explore how understanding and accounting for these environmental stressors is essential for successful performance, and we discuss the role that an AMS such as Apollo could play in managing these challenges intelligently.
