Liga MX club owners voted on Monday in favor of a proposal "to limit the number of foreign-born players allowed in each matchday squad to 10," according to Tom Marshall of ESPN. The previous rule "allowed each team to field five foreigners and an unlimited number of naturalized Mexicans," but the prevalence of players gaining fast-track Mexican citizenship "caused concern about the lack of opportunities for homegrown talent to develop and get first team minutes." Liga MX President Enrique Bonilla said, "There are no longer limits on [registering] foreigners. [But] with the change there will have to be at least eight [players] with a Mexican birth certificate [in the matchday squad]." The limit will come into force for July's Apertura 2016 and Liga MX said that it was "approved unanimously." The new rule will make a distinction "between Mexicans born in the country and naturalized Mexicans, which may cause resentment and even legal challenges." There is a "special clause for dual Mexico-U.S. citizens." The league's statement said, "Players with dual Mexican-American nationality will be considered as one of the eight [Mexican] players if when they first register with the FMF [Mexican federation] they haven't reached 19 years" (ESPN, 5/24).
