Sevilla moved closer to adding another trophy to its collection after Luis Fabiano's 28th-minute penalty gave it a 1-0 win over Real Madrid on Saturday in the first leg of the Spanish Supercup.
Fabiano drove his shoulder-high shot into the left side of net as goalkeeper Iker Casillas dived the other way a minute after Madrid defender Sergio Ramos was penalized for bringing down forward Duda.
Copa del Rey winner Sevilla, which has never won the Supercup, will travel to Madrid for Sunday's second leg of the competition, which pits the league champion against the cup winner.
Sevilla has won all four cup finals it has played in over the past two seasons, having successfully defended its UEFA Cup title, beaten FC Barcelona in the European Supercup and won the Copa del Rey against Getafe in June. It won only four trophies in its history before then, all prior to 1948.
Madrid, which won a record 30th league title in June, played its first competitive match without David Beckham, who was on the field when Madrid won its seventh Supercup four years ago.
New Real coach Bernd Schuster was also without league scoring leader Ruud van Nistelrooy, while Sevilla's leading scorer Frederic Kanoute was missing after being suspended.
Madrid started two new faces in defender Pepe and midfielder Javier Balboa, while Sevilla started newcomers Khalid Boulahrouz and Seydou Keta.
Madrid's defense showed jitters early with Casillas forced to dive to deny Luis Fabiano's low shot in the third minute after the Brazilian had latched on to a long through ball from Boulahrouz.
A minute earlier, Duda watched his free kick from just outside the area sail high over the crossbar.
In the ninth, Raul Gonzalez wriggled the ball from Boulahrouz and created space in the area only for Sevilla goalkeeper Andres Palop to charge off his line and finger the ball away.
Sevilla built on the momentum from its goal, with Casillas denying Duda in the 38th after a giveaway by Jose Gutierrez. Fabiano also had an overhead attempt in the 45th that just missed.
Looking to invigorate the offense, Schuster brought on Julio Baptista and Javier Saviola in the second half, but Madrid failed to threaten until injury time, when Palop dived to push Mahamadou Diarra's low drive from sneaking inside the right post.
Before the second leg next week, Sevilla will host AEK Athens in the first leg of its European Champions League qualifying match on Wednesday.
