The second half was just three minutes old when Real Madrid doubled their advantage and gave themselves breathing room in the contest.
A dangerous shot from Aguado inside the area was pushed behind by the diving Hall and the resulting corner kick led to the second of the afternoon.
It was Aguado’s delivery which found the run of Adrian Perez at the near post and he made no mistake with a cushioned volley on the full to score.
The effort allowed the visitors to play with freedom and they worked Hall further with the goalkeeper reacting quickly to a driven shot from Perez.
With a little under 15 minutes remaining, however, there was nothing he could do about a swift counter attack as Los Blancos added a third.
Two substitutes combined in lethal fashion, Daniel Yanez sprinting away down the right to find Jaime Barroso across the box, who drilled an emphatic finish into the bottom corner.
In the last of the action, the visitors added a fourth goal in added time, Aguado firing past Hall from the left side of the area after a clever reverse pass, putting an exclamation point on the victory.
