Lionel Messi's record $20.45 million annual salary from Inter Miami makes him by far the best paid player in Major League Soccer but also puts him ahead of the entire squads of 25 of the league's clubs, according to data released by the MLS Players Association on Thursday.

The players union regularly releases the full pay details of the entire league.

Messi has a guaranteed compensation of $20,446,667 made up of a base salary of $12 million plus various bonuses, AFP reported.

The figures from the players' union do not include the huge income the Argentine World Cup winner receives in commercial deals, endorsements and sponsorships from companies such as Adidas and Apple.

Messi signed his last contract with Spanish club Barcelona in 2017, a four-year deal that gave him the potential to earn 138 million euros per season including salary and add-ons.

Messi moved to Paris Saint-Germain in August 2021, after his contract with Barca ended and was reported to be earning between 30-35 million euros with the French club.

The 36-year-old joined Miami in July last year on a deal which runs until the end of the 2025 season but he may still be receiving payments from Barca.

Joan Laporta, the Barca president, said in January 2022 that the club were scheduled to make deferred salary payments to the player until 2025.

Toronto's Italian striker Lorenzo Insigne, who was MLS's best-ever paid player until Messi's arrival, was second on the list with a guaranteed income of $15.4 million from the Canadian club.

Messi's Spanish team-mate, Sergio Busquets, the 35-year-old former Barca midfielder, is the third top earner in the league on $8.8 million guaranteed.

Miami's former Barca duo of Uruguayan striker Luis Suarez and Spanish full-back Jordi Alba each earn $1.5 million per year.

Inter Miami's total wage bill is $41.68 million with Toronto second on $31.41 million. Current league champions, the Columbus Crew, had a total salary cost of $15.19 million, ranked 21st in the league.

Messi shares a dressing room with a number of team-mates earning just a tiny fraction of his income -- defender Noah Allen, a regular part of the matchday squad, earns a total of $91,383.

The average MLS salary is $594,390 in 2024 which is up 12.1% from last year.

Miami are able to pay Messi such a high salary because of the 'Designated Player' rule which was brought in to allow Los Angeles Galaxy to sign David Beckham in 2007 on a base salary of $6.5 million a year with his total deal earning him around $50 million in five years.

While Messi's income is huge by MLS standards it is well below the levels of top performers in other major sports in the USA.

Last year Cincinnati Bengals quarterback Joe Burrow signed a five-year deal worth $55 million per season, a new league record.

The NBA's top earner Stephen Curry of the Golden State Warriors makes $51.9 million.
