European Champions Barcelona overtook Europa League champions Porto 2-0 to lift the Super Cup on Friday with Cesc Fabregas scoring his first competitive goal for Barcelona.
Fabregas, who moved from Arsenal in a 29 million euro deal earlier this month, was on target two minutes from time after coming on as a substitute just eight minutes earlier.
Lionel Messi had put Barcelona ahead in the 39th minute as the Spanish giants added the European Super Cup to their domestic Super Cup triumph of last week.
Porto ended the match with nine men after Jorge Rolando and Fredy Guarin were red-carded in the closing stages.
Messi chipped the ball over a line of defenders into the path of Fabregas who calmly controlled it on his chest before volleying coolly past Helton in the Porto goal.
It was Fabregas's first goal since he scored for Arsenal against Huddersfield in the FA Cup back in January.
