The 2026 MLS summer signings have been the most star studded in league history, headlined by Robert Lewandowski joining Chicago Fire and Antoine Griezmann landing at Orlando City. Riding the wave of a World Cup summer, clubs across the league spent big on European pedigree, and five of these arrivals stand above the rest. This ranking counts down the moves most likely to swing the race toward the Audi MLS Cup Playoffs.
Why this list matters
Signings like these do more than sell jerseys. They raise the ceiling of an entire league and pull global eyes toward American soccer at the exact moment the sport is booming here.
Each of these five players changes what their club can realistically chase this season. We ranked them by a blend of pedigree, fit, and expected impact between now and the playoffs, not just by fame. Some are icons in the twilight of their careers. Others are quiet upgrades who could decide tight games in October.
5. Brais Méndez to Columbus Crew

Columbus made the smartest value play of the entire window. Brais Méndez arrives from Real Sociedad as a Spain international with the vision and set piece delivery to unlock defenses that sit deep.
At 29 he is squarely in his prime, and he slots into a Crew midfield built to dominate the ball. Expect him to dictate tempo, feed the forwards, and turn Columbus into a genuine Eastern Conference contender. This is the kind of signing that does not trend on social media but wins matches.
- Signed from: Real Sociedad
4. Allan Saint-Maximin to Charlotte FC
Charlotte answered the departure of Wilfried Zaha with pure excitement. Allan Saint-Maximin brings explosive dribbling and Premier League flair from his years at Newcastle, and as a Designated Player he becomes the immediate focal point of the attack.
He is unpredictable, direct, and exactly the type of player who forces defenders into mistakes in tight spaces. If he stays healthy, he could be the most watchable attacker in the league this fall. Charlotte fans have every reason to buy a season ticket for the second half.
- Age: 29

3. Casemiro to Inter Miami

The reigning champions somehow got scarier. Casemiro joins Inter Miami after a decade at Real Madrid and three seasons at Manchester United, handing Lionel Messi the defensive anchor the club has lacked since Sergio Busquets retired.
He is not the quickest player anymore, but in MLS his reading of the game and his winning habits should shine. He protects the back line, wins second balls, and lets Messi and Rodrigo De Paul roam free. Miami did not need help, which is precisely what makes this move so daunting for everyone else in the East.
- Premier League goals in 2025-26: 9
2. Antoine Griezmann to Orlando City
Orlando landed a bona fide superstar. Antoine Griezmann arrives from Atlético Madrid as a free agent and a Designated Player, and he wasted no time, scoring on his MLS debut to announce himself.
At 35 he no longer sprints past defenders, but his intelligence, movement, and finishing remain elite. He drops between the lines, links play, and lifts the level of everyone around him. For a club still chasing its first MLS Cup, a World Cup winner in the spine of the team is a statement of serious ambition and a magnet for new fans in Florida.
- World Cup won: 2018

1. Robert Lewandowski to Chicago Fire

This is the signing that changes everything. Robert Lewandowski, one of the greatest strikers of his generation, chose Chicago Fire on a Designated Player deal that runs through the 2027-28 season.
He scored 14 goals in 17 LaLiga starts last term, clear proof that the finishing has not dimmed even as the pace has faded. Pair him with in form forward Hugo Cuypers and coach Gregg Berhalter, add one of the largest Polish communities in the country cheering him on, and you have the most compelling story in MLS.
The Fire sat third in the East at the World Cup break, and Lewandowski turns a playoff team into a title threat. If anyone is winning the Golden Boot at his age, it is him.
- Career goals: 700+
The verdict
The 2026 summer window proved MLS can attract elite talent in the same breath as Europe’s giants. Griezmann and Casemiro add championship steel, Saint-Maximin and Méndez add craft and creativity, but Lewandowski is the headline act.
A striker with more than 700 career goals arriving with his finishing intact could decide the title race on his own. Between the marquee names and the smart value moves, American soccer just became a lot more must watch heading into the playoff run.
