A solitary Andre Carrillo strike was enough to see Sporting Lisbon beat Benfica and lift the Portuguese Super Cup.
Sporting coach Jorge Jesus was taking charge of his first domestic game since leaving Benfica in the summer to join their city rivals.
His new club nearly took the lead at the Estadio Municipal de Aveiro when Julio Cesar rushed off his line to prevent Costa Rican international Bryan Ruiz scoring.
Midway through the first half, Benfica squandered a chance to edge in front as Jonas failed to capitalise with a header inside the Sporting area.
The Lions almost broke the deadlock when Joao Mario's shot brought a save out of Cesar soon after the restart.
However, Sporting took the lead on 52 minutes as Carrillo finally found a way through the Benfica rearguard.
The Eagles brought on Kostas Mitroglou in the dying stages, but the Green and Whites were able to hold on to give Jesus his first trophy at the club.
