Inter Miami announces the signing of Brazilian midfielder Casemiro, described as a five-time UEFA Champions League winner. Following the club’s announcement, Major League Soccer initiates an investigation into whether Inter Miami engaged in “tampering” related to the transfer. The issue centers on whether the reigning MLS league champion may have violated league rules governing player recruitment and contact with players under contract with other clubs. The reporting indicates the league is reviewing the circumstances around how the deal was concluded, including whether improper approaches or communication occurred before the signing was finalized. Inter Miami’s signing is presented as completed, but the league’s inquiry is ongoing and could affect how the matter is handled under MLS regulations. The sources do not specify the outcome of the investigation, any findings, or potential penalties at this stage.
