The race to the 2026 FIFA World Cup is on, and is now in the final stages. At this point, it’s not just the national team managers who are feeling the pressure. Throughout the world, across continents, club coaches are having to navigate a series of disruptions that include missing teammates, stretched squads and a necessary change in tactical plans as qualifiers butt heads with domestic club calendars.

For anyone tracking upcoming football fixtures, the impact is already clear to see. This comes in the form of unexpected rotations, changed play formations and even managers simply trying to preserve momentum while aiding teams who are pushed harder than normal.

This qualifying cycle is particularly brutal due, in part, to the expanded FIFA World Cup format. With 48 teams, there are more players required during the qualification period. This is also coupled with the compressed domestic schedules of major leagues. As a general rule, the global football calendar is always packed, but including match days for qualifiers has made management at the elite level even more complex. Now clubs need to juggle league commitments, cup competitions, European tournaments and extra international travel.

Putting a strain on the team

Top clubs have a number of issues, but the biggest one is fatigue. Key players often return from international duty having had a solid period of play with little recovery time when returned to their squad. For some, the return is not a great one either, as they may have suffered small knocks and injuries that require careful handling to not exacerbate them for club and international games. On top of that, the distance between qualifying matches and league fixtures is increasingly concerning. For example, a South American international will finish CONMEBOL qualifiers late on one night only to have a domestic league game within 48 hours.

This short turnaround puts more strain on some players than others. For instance, goalkeepers tend to feel less fatigue physically, but are challenged mentally by high-stakes matches. Conversely, midfielders and full-backs, players who cover a lot of ground, have more physical issues and require more rotation to give them a break. This forces managers to rely on the depth of the squad to keep performing at a high level when key players are rested. Attacking stars face even more pressure, combining national expectations with club demands. A drought in goal-scoring or even a slight dip in form can have consequences on both the domestic and international stage.

What this means is that managers are continually rotating line-ups out of necessity. And this does not always work well for teams, especially those participating in tight title races. Frequent changing of line-ups and formations means a team can’t gel or become a cohesive unit, which can impact performances.

Tactical impacts and travel demands

As mentioned, tactics have to change when there is regular rotation in place. Many clubs have to resort to more conservative 4-4-2 blocks with deeper defence and more compact midfields during the international window. Of course, there are sometimes benefits for younger or inexperienced players, as managers will often use fringe players for meaningful minutes in a game. In the long term, this is great for giving game time and improving the depth of the squad, but for clutch games, this does bring in inconsistency to the team. Young defenders will struggle against more experienced attackers, and midfielders may well lose duels to veteran players on the opposition.

There are also major travel demands for many top players, and this is one of the most complex challenges. European players tend to be able to travel within the continent, but those representing African, Asian or South American nations have long flights, dramatic climate changes and varied playing conditions to contend with. This means that club medical teams need to monitor hydration, sleep cycles, muscle load and fatigue markers more stringently to check for issues after a player returns. Injury risks are more prevalent after a high-risk game, and then there is the psychological impact and the outright disruption in momentum within clubs, which is hard to recover from.

Qualifying rounds are once more appearing, so the tension between club and country will continue to mount for top players. Adjusted line-ups, altered training loads and flexible tactics are going to be seen across club games over the coming months.
