FWC 2026 Club Strength Index: Which National Teams Have the Strongest Club Base?

The table below presents the FWC 2026 Club Strength Index (CSI), a ranking of the national teams participating in the tournament based on the strength of the clubs represented by the players called up to their squads.

The CSI measures the club-level environment from which each national team is drawn. It does not rank teams by current tournament results, historical prestige or international reputation. Instead, it asks a different question: how strong are the clubs in which the selected players normally compete?

The first column shows the CSI rating value. The reference benchmark is 100 points. A value above 100 indicates that the squad is, on average, built around players from a very strong club environment. A value below 100 points to a more moderate or weaker average club-strength profile.

The next column shows each country’s position in the FWC Ranking, based on tournament-performance criteria: stage, points, goal difference, goals scored, goals conceded and group-stage position. The data on this page is updated after the completion of each round/phase (the data on the source page is updated in real time).

The NFRI column shows each country’s position in the National Football Reputation Index, which reflects the broader global football reputation of national football systems.

The final column shows the number of players in the squad who play for clubs ranked outside the KA Top 1000 clubs.

At the top of the CSI are teams such as France, Spain, England, Germany and Portugal. Their squads are strongly connected with elite-level club football and contain players from clubs with very high KA ratings. These teams combine individual quality, squad depth and a strong club-football background.

However, the CSI also shows that club-level strength does not automatically translate into national-team performance. A strong squad on paper may underperform, while a team with a more modest club profile may achieve better tournament results.

The clearest negative examples are Uruguay and Turkey. Both have a strong club profile, with a CSI rating above the 100-point benchmark, but this has not been reflected in their tournament performance so far.

On the other side, Mexico shows the opposite pattern. The team won its group despite having more moderate CSI profiles (3 wins, zero goal againts).

Mexico’s squad is built mainly around players from Mexican clubs and mid-level European clubs, without the same elite-club concentration visible in the strongest European national teams.

This contrast is precisely what makes the CSI useful. It does not replace the tournament table and it does not mechanically predict match results. Instead, it provides a complementary analytical layer. It helps identify which national teams are overperforming or underperforming relative to the club strength of their squads.

In this sense, the CSI gives a different perspective on FWC 2026. It shows not only who is winning, but also which national teams are supported by the strongest club-football base — and where the gap between club strength and national-team performance is the widest.

It should also be noted that the CSI measures the club affiliation of each selected player, not the player’s actual role within that club.

In other words, the index identifies the strength of the clubs from which the squad players are drawn, but it does not directly measure whether a player is a regular starter, a rotation player, a reserve, or a player with limited match involvement. For this reason, the CSI may slightly overstate the practical squad strength of some national teams.

A possible example is Saudi Arabia. Some Saudi players are registered with highly rated clubs, which may improve the team’s CSI profile. However, if those players have only limited playing time or a secondary role within those clubs, the rating may not fully reflect their actual competitive impact at national-team level.

This does not invalidate the CSI, but it is an important interpretative limitation. The index should therefore be read as a measure of club-strength exposure, rather than a complete assessment of individual player status, playing time or squad role.
