Gonzalo Higuain and Cristiano Ronaldo scored first-half goals as Real Madrid beat 10-man Barcelona 2-1 to lift the Spanish Super Cup before a full house at the Santiago Bernabeu on Wednesday.
With last Thursday's first leg at Camp Nou having ended in a 3-2 Barca victory, Madrid took the title on away-goals after a 4-4 aggregate draw.
All the action came in an exciting first half, where Lionel Messi replied with a brilliant free-kick for Barcelona, who had previously lost Adriano to a straight red card for a last-man foul on Ronaldo.
It was a timely success for Madrid, who have already fallen five points behind arch rivals Barca in La Liga after a draw and a loss in their first two league games.
With the tie finely balanced, both sides started with near full-strength teams.
Madrid coach Jose Mourinho kept faith with Higuain, who had scored in consecutive league games, leaving Karim Benzema to start on the bench with Luka Modric, who made his first appearance for Madrid after signing on Monday.
Barca, however, had to cope with a problem just before kick-off when Jordi Alba replaced Dani Alves, who seemed to pick up an injury in the warm-up.
Adriano was switched from left-back to right-back to accommodate Alba and the change seemed to have a major effect on the Catalans' start.
Madrid were quick out of the blocks and goalkeeper Victor Valdes made a superb block from Higuain on seven minutes to stop a certain opener.
However, three minutes later he could do nothing in a similar situation after Javier Mascherano had misjudged the flight of a long ball out of defence from Pepe. Again Higuain found himself in space and this time he slotted home.
Madrid were on top and Ronaldo surged down the wing to be blocked by Mascherano, who appeared rattled by his error and picked up a yellow card.
Marcelo went close before Ronaldo doubled Madrid's lead on 18 minutes.
Again it was a long ball out of defence that troubled Barca.
This time Gerard Pique failed to clear a Sami Khedira ball and the Portuguese star pounced on the loose ball to advance on goal and finally, after a quick check-back, beat Valdes with a low shot to claim Madrid's second of the evening.
It got worse for Barca when Adriano received his marching orders on 27 minutes for a trip on Ronaldo, who was running on to another long ball out of defence.
Valdes saved well again from Khedira and Madrid's wave of advances finally came to an end.
Barca made their first real attack of the evening in the 36th minute but nobody was able to connect with Andres Iniesta's dangerous cross.
Messi then struck with a perfectly curled free-kick to reduce Madrid's lead.
The second half could not continue at the same pace and, as Barca gained more possession and settled into a more comfortable passing game, chances became rare.
