Fabian Castillo is one of FC Dallas' biggest development success stories. Head coach Oscar Pareja brought the attacking midfielder to North Texas from Colombia in 2011, even briefly letting Castillo stay on his couch. Castillo blossomed for FC Dallas, turning into one of the most dynamic offensive players in the MLS, culminating with his being named the league's best player under 24 following the 2015 season. Buoyed by the award and playing his first match for the Colombian national team, Castillo decided to take his game to Europe, traveling to Turkey in July to sign a contract with Trabzonspor. All of that would've been well and good except for one thing: FC Dallas hadn't let Castillo go. While essentially AWOL from the team that held his rights, Castillo was pictured at the airport, taking a physical and in a Trabzonspor jersey with team officials, all without FC Dallas having agreed to his transfer. Eventually FC Dallas agreed to loan Castillo to Trabzonspor for the Turkish league season with an option to buy.
