Robert Alberto Arias Sancho (born 16 March 1980) is a Costa Rican retired footballer.
Arias started his career with Herediano, playing for them until 2011 despite offers from Alajuelense and Saprissa, the most successful team in Costa Rica.[1]
While coaching Suchitepéquez in Guatemala, he claimed it was impossible to win in an away game against Sololá, due to death threats and the referee's bias.[2]
Arias' nephew, Aarón Salazar, is also a professional footballer.[3]
