What happened with Inter Miami and Casemiro?

On Wednesday, Inter Miami confirmed the signing of 34-year-old Brazil midfielder Casemiro after he left Manchester United at the end of last season. According to reporting from the BBC, The Guardian and Sky Sports, the free-agent deal runs to the end of the 2027 MLS campaign and includes an option to extend into 2029.

The Guardian described the pact as amounting to a one-year contract that ends with the 2027 “sprint season,” ahead of MLS switching to a fall-to-spring calendar in 2027-28, with an option that could keep Casemiro through the 2028-29 season. Sky Sports likewise said the contract covers him through the end of 2027, with an extension option until 2029.

Moments after the club’s announcement, MLS said it was reviewing a tampering allegation against Inter Miami. “The league is gathering all relevant information and will refrain from further comment until the review is complete,” the league said, as quoted across the BBC, Guardian and Sky Sports reports.

MLS also stated that while Inter Miami and the LA Galaxy had reached a settlement for the discovery priority to sign Casemiro, “the terms will be released upon conclusion of the tampering investigation.”

Why does discovery priority matter in this Inter Miami deal?

MLS discovery rules are central to the story. A club may keep up to five players on its discovery list at any time and can add or remove names. Those rights give a specific club first refusal if that player wants to join the league.

Los Angeles Galaxy held discovery rights for Casemiro. In announcing the signing, Inter Miami said it had acquired those rights from the Galaxy. The Galaxy separately said it had reached a settlement with Inter Miami for the discovery priority, and that the terms would be published only after the MLS tampering review concludes.

The Guardian noted that discovery priority does not permanently lock a player to one club: MLS sides can trade or settle those rights so another team can negotiate. It cited Marco Reus in 2024 as an example, when the Galaxy paid Charlotte FC $400,000 for discovery rights after Charlotte had listed him. MLS has not said whether the current allegation concerns any talks Inter Miami may have had with Casemiro before securing his discovery rights, or the rights acquisition itself.

Under MLS rules described by Sky Sports, clubs must negotiate discovery rights with any team that previously listed a player before signing him outside the draft or free agency. The league has not specified potential penalties or a timeline for when the investigation might finish.

Who is Casemiro and what did Inter Miami say?

Casemiro won five Champions League titles with Real Madrid before joining Manchester United in 2022. He made 160 appearances for United, scoring 26 goals and providing 14 assists, and won one EFL Cup and one FA Cup, the BBC reported. Sky Sports noted he scored in the 2023 League Cup final, reached two FA Cup finals (winning in 2024), and was part of the United side that reached the 2025 Europa League final.

He played for Brazil at the 2026 World Cup as the Seleção reached the last 16; the Guardian said Brazil were eliminated by Norway and that Casemiro has 91 caps. United did not renew or trigger a contract option, Sky Sports reported, and have since signed Andrey Santos from Chelsea for £50m and Youri Tielemans from Aston Villa for £35m, according to the BBC.

“What motivates me the most, and I think this is true for every player, is winning and continuing to grow,” Casemiro said after the move, as quoted by the BBC and Sky Sports. He added that the project Miami presented, and the effort to bring him in, meant a lot, and that he would give everything to repay the club’s trust on matchdays and in training.

Inter Miami managing owner Jorge Mas said Casemiro “embodies everything this club stands for: leadership, a winning mentality, and an extraordinary track record at the highest level of the game.” Co-owner Sir David Beckham said he had admired Casemiro for a long time and was “delighted that he’s decided to make Miami his next home.” At Miami, Casemiro is set to join Lionel Messi, Rodrigo De Paul and, per the BBC, former Real Madrid and Manchester United teammate Sergio Reguilón, with the Guardian also naming Luis Suárez among the club’s stars as Miami defend their 2025 MLS Cup title.

Has Inter Miami faced MLS transfer scrutiny before?

Yes. The BBC reported it is not the first time Inter Miami have been probed over transfer dealings. In 2021 the club were fined $2m after breaking MLS rules with the signing of France midfielder Blaise Matuidi from Juventus the previous year.

MLS said Matuidi had been paid more than was allowed, effectively giving the team four “designated players” rather than the permitted three. Designated players’ wages do not count toward the MLS salary cap. The so-called “Beckham rule” dates to when the ex-England captain joined LA Galaxy in 2007.

That history does not decide the current case. For now, Casemiro’s signing is public, the Galaxy–Miami discovery settlement is acknowledged, and MLS says it will withhold further comment—and the settlement terms—until its tampering review is complete. Fans and franchise watchers will be watching whether the probe reshapes how discovery rights, star free agents and club compliance collide in MLS’s biggest markets.
