Put Your Soccer Knowledge to the Test: Can You Identify All 30 MLS Clubs Against the Clock?

Major League Soccer (MLS) was originally conceived in 1993 as a condition of the United States securing the rights to host the 1994 World Cup. The league would take an additional three years to launch, with the NASL's successor initially fielding 10 founding clubs.

It required considerable time before audiences, sponsors, and high-profile players began paying attention to MLS, but a steadily growing fanbase, combined with an expansion to 30 clubs, has helped soccer's popularity surge dramatically.

With Lionel Messi, Son Heung-min, and Thomas Müller currently showcasing their talents in MLS—and Antoine Griezmann set to join in the summer of 2026—there has never been a more exciting time to follow the league.

Sports Illustrated challenges you to name all 15 teams in the Eastern Conference and all 15 in the Western Conference as fast as you can. Take the quiz below and see if you can complete it within six minutes. Best of luck!

The Best Players in MLS History

Messi may be the headline act currently playing in MLS, but he is far from the only superstar to have lit up the league over the past three decades.

Zlatan Ibrahimović and David Beckham are two prominent alumni who made their mark in Los Angeles—the latter is also now part of the ownership group of a celebrated MLS Cup champion—while Sebastian Giovinco, Carlos Vela, and Robbie Keane have each left a significant imprint on the league.

Perhaps the two most impactful figures in MLS history are former cornerstones of the U.S. men's national team—Landon Donovan and Chris Wondolowski. They paved the way for today's generation, shattering records and raising the level of play to unprecedented heights before eventually stepping away into retirement.
