Casemiro Joins Inter Miami as MLS Launches Tampering Investigation Over Blockbuster Move

Inter Miami have completed the signing of Brazilian midfielder Casemiro, but the high-profile transfer has immediately come under scrutiny after Major League Soccer (MLS) launched an investigation into whether the club violated league rules during the signing process.

The 34-year-old, regarded as one of football's most accomplished defensive midfielders, has signed a contract with Inter Miami through the end of the 2027 sprint season, with an option to extend his stay until June 2029.

Casemiro arrives in the United States after an illustrious career in Europe, where he won five UEFA Champions League titles with Real Madrid before spending the last four seasons with Manchester United. He also featured in all five of Brazil's matches at the 2026 FIFA World Cup, scoring one goal during the tournament.

While the signing has boosted Inter Miami's squad, it has also raised questions over the club's compliance with MLS regulations. Under league rules, LA Galaxy held Casemiro's discovery rights, giving the club exclusive priority to negotiate with the player within MLS.

Inter Miami and LA Galaxy eventually reached a settlement that cleared the way for the transfer. However, MLS is investigating whether Inter Miami engaged in negotiations before acquiring those rights, a potential breach of the league's tampering rules.

In an official statement, MLS said it is gathering all relevant information before making any further comments. The league also confirmed that the terms of the settlement between Inter Miami and LA Galaxy will only be made public once the investigation is completed.

Casemiro is yet to make his debut for Inter Miami as he is awaiting the necessary visa clearance.

Welcoming the Brazilian star, Inter Miami co-owner David Beckham described Casemiro as a serial winner whose remarkable success with Real Madrid and Manchester United makes him an ideal addition to the club's ambitious project.

The arrival of one of world football's most decorated midfielders is expected to strengthen Inter Miami considerably. However, until the league completes its investigation, Casemiro's move is likely to remain one of the biggest talking points in Major League Soccer.
