Porto have qualified for the quarter-finals of the Europa League thanks to a 2-2 draw with Napoli in the second leg of their last-16 tie.
The Portuguese side, who claimed a 1-0 victory in the first leg a week ago, could have doubled their advantage in the early stages of the first half but Carlos Eduardo failed to hit the target with his header from close range.
However, it was Napoli who broke the deadlock in the 21st minute as Gonzalo Higuain split the visiting defence to find Goran Pandev, who held his nerve to chip the ball over Fabiano.
Porto could have made it 2-1 just moments later but Steven Defour could only hit the post after finding space inside the box.
However, the visitors didn't have to wait much longer for a second goal as Ricardo Quaresma extended their lead further by beating two defenders before firing an unstoppable shot past a helpless Reina.
Napoli refused to give up the fight and managed to level the scores on the night at 2-2 when Duvan Zapata converted a Jose Callejon cross in stoppage time but it proved to be too little, too late as Porto secured their progress in the competition.
