MLS investigates Inter Miami over Casemiro transfer tampering allegations

Major League Soccer has launched an investigation into Inter Miami over allegations of tampering in the club’s signing of Brazil midfielder Casemiro, a move that has drawn immediate scrutiny from the league’s governing body. The 34-year-old, who left Manchester United at the end of the 2026-27 season, signed a contract with Inter Miami that will run through the end of the 2027 MLS campaign, with an option to extend until June 2029. However, the deal is now under review after the league alleged that Inter Miami may have violated transfer rules by contacting Casemiro before securing his discovery rights, which were held by the LA Galaxy.

The dispute centers on MLS’s discovery rights system, a mechanism designed to prevent bidding wars over high-profile players. Under the rules, a club must first acquire the right to negotiate with a player before engaging in talks. The LA Galaxy had held Casemiro’s discovery rights, meaning Inter Miami was required to reach an agreement with the Western Conference team before finalizing the transfer. While Inter Miami and the Galaxy have since settled the matter, MLS has stated it is “gathering all relevant information” and will not comment further until the review concludes. The terms of the settlement remain undisclosed.

Casemiro’s arrival in Miami has been framed as a major coup for the club, which aims to bolster its roster with experienced stars. The Brazilian, a five-time Champions League winner with Real Madrid and Manchester United, joins former teammates Sergio Reguilon and Lionel Messi, as well as Argentina’s Rodrigo de Paul. Inter Miami co-owner David Beckham praised the signing, calling Casemiro “a winner who has achieved so much in the game.” However, the investigation casts a shadow over the deal, raising questions about the club’s adherence to MLS regulations.

This is not the first time Inter Miami has faced scrutiny over its transfer practices. In 2021, the club was fined $2 million for violating salary cap rules during the signing of Blaise Matuidi. The current probe could lead to similar penalties if tampering is confirmed. MLS has not specified potential consequences or a timeline for the review, leaving the outcome uncertain.

Casemiro’s contract details highlight his status as a marquee addition. The free transfer follows his departure from Manchester United, where he made 160 appearances, scoring 26 goals and providing 14 assists. His move to MLS comes after a World Cup campaign with Brazil, where he played all five matches, including the team’s round-of-16 exit to Norway. Despite the controversy, Inter Miami has positioned the signing as a step toward competing for titles, with Casemiro expected to play a pivotal role in the 2027 season.

The Galaxy’s statement confirmed the settlement with Inter Miami, emphasizing that the terms would be revealed only after the investigation concludes. The league’s decision to probe the matter shows how much transparency in MLS transfers, particularly for players with international profiles. While the settlement suggests the clubs have resolved their differences, the ongoing review leaves room for further action, including potential fines or restrictions on future transfers.

As the investigation unfolds, the focus will remain on whether Inter Miami’s actions violated the league’s rules. The outcome could set a precedent for how discovery rights are managed in future transfers, affecting clubs’ strategies in acquiring top talent. For now, Casemiro’s move to Miami remains official, but the shadow of the probe lingers, highlighting the delicate balance between ambition and compliance in professional soccer.
