A new data index compiled by analysts suggests that Arsenal, Aston Villa, and Manchester United stand to be the Premier League clubs most affected by the FIFA World Cup 2026.

The index weighs factors such as the number of international players in each squad, the rounds those nations are expected to reach, and the potential for fixture congestion and player fatigue upon their return to club football.

Clubs with a high proportion of players likely to feature in deep tournament runs face the steepest challenge when the Premier League resumes, with recovery time and injury risk central concerns for managers.

Arsenal, with their large contingent of international stars across multiple confederations, are among the most exposed. Aston Villa's global recruitment drive in recent seasons has similarly loaded their squad with players who carry heavy international obligations. Manchester United, despite a difficult domestic campaign, retain a roster packed with players expected to travel to the World Cup.

The analysis underlines a growing tension in the modern game between the ambitions of national federations and the welfare concerns of club managers, many of whom have little control over how their players are managed during international tournaments.

For African football fans, the index carries particular relevance — several of the players central to Arsenal, Aston Villa, and Manchester United's squads are key figures for their national teams, meaning a deep World Cup run could come at a cost once the club season resumes.
