Duarte, 19, has made a handful of appearances for Espanyol this season as a left-back, although he has played for the club's youth teams as a central defender. 

He featured promininetly in Espanyol's run to the Copa del Rey semi-final, impressing in matches against Valencia and Sevilla. 

Valencia's exciting young left-back Jose Luis Gaya will also train with the Spain squad. 

Malaga forward Juanmi, Celta Vigo's versatile defender Jonny Castro and Atletico Madrid's Saul Niguez will also join up with Del Bosque's squad.
