A Guide to the First-Ever Three-Week September International Soccer Window

FIFA's international calendar has delivered an unusually packed slate of matches this September, with the first-ever three-week international window giving national teams around the world extended time to prepare and compete.

Marquee Matchups and Storylines

Among the fixtures drawing attention is a matchup pitting managerial figures Jurgen Klopp and Xavi Hernandez against one another in their current national team or advisory roles, a pairing that has generated interest given both men's recent managerial careers at the club level.

Cape Verde's Return

Cape Verde's national team is also back in action during the window, continuing its recent rise in African soccer following a standout qualifying campaign that raised the profile of the program on the continental and world stage.

A Showcase for Young Talent

The extended window has also given several federations, including the United States, room to test younger players in senior team environments, with a handful of debutantes earning looks during the break.

With three full weeks of matches rather than the traditional shorter international breaks, coaches have more time to experiment with lineups and systems, while fans are treated to a denser slate of notable fixtures than in a typical September.
