The 19 year-old Argentine is expected to join Zaragoza on-loan today. Giuliano is the son of Atletico coach Diego Simeone.
His move to Zaragoza was agreed at the end of last season, but red-tape stalled the move until today.
Simeone will join Zaragoza coach Juan Carlos Carcedo's preseason on Tuesday.
Last season he scored 25 goals with the Rojiblanco reserves in the RFEF Tercera Division.
