World Cup 2026 Preparation: The New Equation of Squad Building in the Transfer Window

When the Calculus of Squad Building Changes

Walking into a club's training ground last week, the first thing that caught my eye was the light on in the data analysts' room. Nine in the evening, the pitch almost empty, but the analysis department was still working. This scene reminded me of 2026, when I spent three weeks embedded with Brentford's analytics team. Watkins was signed then for £1.8 million, based on xG data. Today, on the eve of the 2026 World Cup, the pace and nature of the transfer window has moved to an entirely different place. Hosted across the United States, Canada, and Mexico, this World Cup will differ from all previous editions — 48 teams, 104 matches, and with that, a prolonged period of players leaving their clubs to join national teams. In this reality, clubs are now making every transfer window decision within a different framework.

The New Geometry of the Transfer Window

June-July 2026 is the World Cup. This means the pre-season preparation for club football and the integration of new signings are on a compressed timeline. If a club signs a player in May, they won't return until late August after the World Cup. The time for that player to build an understanding with new teammates will shrink to a few weeks. This problem will be particularly acute for clubs with multiple international stars. Take Manchester City, for instance. A large portion of their squad will play in the World Cup for various national teams. On the other hand, clubs planning big without international stars could find this period to be a golden opportunity.

When I tracked England's set-pieces at the 2026 Russia World Cup, I saw how coaching staffs create specific routines before each match. I built a 12-column set-piece spreadsheet then. From that experience, I can say that set-pieces will become even more important in the 2026 World Cup. Because in a long tournament, fitness and recovery time will decrease. A large portion of goals will come from dead balls. The clubs now investing in set-piece coach hires are actually laying the foundation for the post-World Cup season.

Data's Reign in the Transfer Market

Over the past few seasons, a clear change has come to the transfer market. Clubs are no longer buying players just by looking at goals and assists. They are looking at progressive carries, pressing triggers, and high-intensity action counts. This data-driven perspective has become particularly strong in English football, because Premier League analysis departments are the most advanced in Europe. From my Brentford experience, I can say that if a club can build the right data model, they can find the player who fits their system best at a much lower cost.

This trend will intensify in the upcoming World Cup transfer window. Because a 48-team World Cup means more matches, more player exposure. Players from smaller nations in Latin America, Africa, and Asia will get a big stage in this tournament. Scouts have already started collecting data from those countries' domestic leagues. Speaking of Bangladesh cricket, our domestic league's data infrastructure has not yet reached that standard. But if this World Cup transfer wave can be leveraged properly, Bangladeshi footballers could get opportunities in foreign leagues.

The Counter-Intuitive Truth: Not Transfer Fees, the Real Story is Free Agents

While everyone is talking about multi-million transfer fees, a different picture is emerging. After the 2026 World Cup, many experienced players' contracts will expire. Because clubs generally don't want to sign long-term deals with players over 30. As a result, many established stars will hit the market as free agents after the World Cup. Clubs have already started reaching out to these players. This is where the real game is. The club that already has that free agent list prepared will be able to finish assembling their squad right after the World Cup ends. I saw this process after the 2026 Qatar World Cup too. Many clubs quickly turned to free agents then.

Another factor is loans. Before the World Cup, clubs will want to send their young players on loan to other teams for experience. But after the World Cup, those players returning from loans will need to secure places in the main squad. This competition will be tough.

Looking Ahead

As I opened my notebook and started tracking preparations for the 2026 World Cup, one thing became clear. The tension between clubs and national teams will increase further in the coming months. The question is, will the clubs investing most heavily now in analysis and fitness perform best in this long World Cup season? Or will those willing to give players rest from a human perspective have the last laugh?

My notebook has already started searching for the answer to this question. Because I know rhythm is built first, performance comes later.
