The 10 Most Important Signings in MLS History: Who Tops the List?
Major League Soccer has come a long way since its inception in 1996. Over the years, the league has transformed from a fledgling experiment into a respected destination for some of the world’s best football talents. As MLS approaches its 30th anniversary, a new wave of stars like Son Heung-min and Lionel Messi have arrived, taking the league’s profile to unprecedented heights. But which signings have been truly transformational for the league?
Here’s a look at the 10 most important MLS signings, players who not only dazzled on the pitch but also helped shape the league’s identity and growth.
1. David Beckham (LA Galaxy, 2007-2012)
When David Beckham swapped Real Madrid for LA Galaxy in 2007, it wasn’t just a transfer, it was a seismic shift for soccer in the United States. Beckham’s arrival put MLS on the global map and forced the league to create the “Designated Player” rule, often called the “Beckham Rule,” allowing teams to sign star players outside the salary cap. More than his skill, Beckham brought glamour, attention, and a new ambition, paving the way for stars like Kaka, Frank Lampard, and eventually Messi and Suárez to join MLS.
2. Zlatan Ibrahimovic (LA Galaxy, 2018-2019)
If Beckham was the classy diplomat, Zlatan was the brash showman. Ibrahimovic lit up the league with his larger-than-life personality and goal-scoring prowess. In just 56 games, he netted 52 goals and handed out 13 assists, all while keeping the league in the media spotlight with his cheeky remarks about MLS’s salary cap and quality. Zlatan made MLS must-watch TV, blending star power with entertainment.
3. Lionel Messi (Inter Miami, 2023-present)
Signing Lionel Messi was a coup of historic proportions. The greatest player ever, joining just months after winning the 2022 World Cup, instantly elevated MLS’s credibility. Messi didn’t just bring star power, he delivered results, scoring 40 goals and assisting 26 in 44 games, winning the Leagues Cup and Supporters’ Shield with Inter Miami. His pink jersey became the best-selling shirt in league history, proving he’s more than just a headline; he’s a game-changer. His presence has ensured Inter Miami head into next season as favourites to win the MLS in the online betting markets.
4. Son Heung-min (LAFC, 2025-present)
Son Heung-min’s move to LAFC is groundbreaking, representing not just a player acquisition but a bridge to the massive Asian market. Arguably the best Asian player ever, Son brings speed, skill, and goal-scoring ability, scoring or assisting in every one of his first three MLS games. His $26 million transfer might be a record fee, but the marketing and sponsorship opportunities his arrival unlocks make it a savvy investment.
5. Landon Donovan (San Jose Earthquakes, LA Galaxy)
Landon Donovan is the quintessential American soccer hero. Returning to MLS after struggling in Germany, Donovan’s presence gave the league a vital boost when it was financially vulnerable. Alongside Clint Dempsey, Donovan helped establish MLS as the home of the country’s top talent, securing the league’s survival and growth. Their combined star power laid the foundation for MLS’s rise in the post-Beckham era.
6. Thierry Henry (New York Red Bulls, 2010-2014)
Thierry Henry was the first superstar Beckham helped lure to MLS. The French legend brought world-class skill and a winning mentality to New York, scoring 52 goals and becoming a fan favorite. Henry’s signing sent a clear message: MLS was serious about attracting top international talent to its biggest market.
7. Robbie Keane (LA Galaxy, 2011-2016)
When Beckham arrived, LA Galaxy still needed a lethal finisher—enter Robbie Keane. The Irish striker, with over 100 Premier League goals, instantly clicked with Beckham, scoring 21 minutes into his MLS debut. Keane’s goal-scoring exploits (104 goals in total) and trophies (three MLS Cups) made him one of the league’s most prolific and successful players.
8. Carlos Vela (LAFC, 2018-2024)
Carlos Vela’s signing was a masterstroke for a new franchise. Joining LAFC in their inaugural season, the Mexican international shattered the single-season scoring record with 34 goals and helped the team win two Supporters’ Shields and reach two MLS Cup finals. Vela proved that expansion teams could land elite talent and compete immediately.
9. Sebastian Giovinco (Toronto FC, 2015-2019)
Giovinco was a rare exception to the early designated players, joining MLS still in his prime at 28. His silky skills and scoring ability (68 goals, 40 assists) led Toronto FC to the only treble in MLS history—the MLS Cup, Supporters’ Shield, and Canadian Championship. Giovinco’s impact was as much on the pitch as it was on the league’s reputation.
10. Jorge Campos (LA Galaxy, 1996-1997)
Jorge Campos might not be the flashiest name on this list, but he was one of the first international stars in MLS, helping to build a fanbase among Latino communities in the U.S. Known for his flamboyant style and colourful jerseys, Campos brought personality and flair at a time when MLS was still finding its footing.
MLS’s history is full of iconic signings, each representing different eras and ambitions. Beckham put the league on the map, Ibrahimovic brought edge and entertainment, Messi gave it global legitimacy, and Son opens new frontiers. From American legends like Donovan and Dempsey to international stars like Henry and Vela, these signings have shaped MLS into the competitive, entertaining league it is today.
As the league celebrates its 30th anniversary, the story continues, with new stars arriving and raising the bar. Who will be the next icon to make history? Only time will tell. But one thing is clear: MLS’s journey from humble beginnings to international spotlight has been fuelled by these unforgettable players.
