Casemiro moves to Inter Miami as MLS probes tampering

Inter Miami have signed Brazilian midfielder Casemiro on a one-year contract, with an option to extend through the 2028-29 season. The deal runs through the conclusion of the 2027 "sprint season," which precedes the league's switch to a fall-to-spring calendar. The 34-year-old joins a defending MLS Cup champion side that already features Lionel Messi, Luis Suárez and Rodrigo De Paul.

However, Major League Soccer is simultaneously investigating the Florida club for potential tampering. The league confirmed it is reviewing an allegation against Inter Miami. Crucially for football business observers, the league stated that the terms of the deal to acquire Casemiro’s discovery rights from the LA Galaxy will remain secret until the probe concludes.

This dispute underscores the strict regulatory differences between European and American football markets. In Europe, a departing player like Casemiro operates in an open market and is free to negotiate directly with any club. In MLS, foreign transfers are restricted by a discovery process where teams maintain a list of up to five players for whom they hold priority rights, forcing rival clubs to negotiate internal trades to facilitate a signing.

The financial mechanics of this system were illustrated last year when the LA Galaxy paid Charlotte FC $400,000 to acquire the discovery rights to Marco Reus. It remains unclear whether the current tampering allegation centres on Inter Miami negotiating with Casemiro before officially securing his rights, or on the underlying financial terms of the settlement with the Galaxy.

For European investors and executives, the probe highlights the centralised, franchise-model controls that govern player acquisition in the United States. Unlike Europe's free-flowing transfer market, MLS retains tight oversight over its internal player economy, making compliance with discovery rules a critical risk factor for teams spending heavily on European talent.

Casemiro arrives after a four-season stint at Manchester United, where his most notable achievement was winning the 2023-24 FA Cup. The five-time Champions League winner with Real Madrid also featured for Brazil at the 2026 World Cup, where the team was eliminated by Norway in the last 16.

“Casemiro embodies everything this club stands for: leadership, a winning mentality, and an extraordinary track record at the highest level of the game,” said Inter Miami managing owner Jorge Mas. Co-owner David Beckham added: “He is a winner who has achieved so much in the game and after such an incredible career with Real Madrid and Manchester United I’m delighted that he’s decided to make Miami his next home.”
