The MLS MVP award has been presented since 1996 and is voted for by MLS club technical staff, media, and current players.
Messi won more than 70% of the vote, while his nearest challenger, San Diego winger Anders Dreyer, had just over 11%.
The former Barcelona and Paris St-Germain star adds the prize to a list of personal accolades, which include the 2022 World Cup, three The Best Fifa Men’s Player awards, and two World Cup Golden Balls.
Messi has also claimed three Uefa Men’s Player of the Year awards, six European Golden Shoes, six La Liga Best Player recognitions, eight Pichichi Trophies as Spanish football’s top scorer, and 15 Argentine Footballer of the Year awards.
He has yet to confirm, though, whether he will feature for Argentina in the 2026 World Cup, which will be held in United States, Canada and Mexico.
