The deal is not without its complications, as the LA Galaxy currently hold the "discovery rights" for the midfielder. Under MLS regulations, the Galaxy have the priority right to negotiate with the player, and the club was hopeful of convincing Casemiro to move to California instead. Reports suggest the Galaxy held numerous conversations with the player’s representatives and submitted multiple contract offers.
This mechanism is designed to prevent MLS teams from driving up prices by bidding against each other for the same international targets. However, Casemiro's insistence on joining Miami has forced a standoff. If a deal is to be finalised, Miami will likely have to compensate the Galaxy, similar to how Los Angeles paid Charlotte FC $400,000 for the rights to sign Marco Reus two seasons ago.
