Porto have headed to the top of the Primeira Liga with a 2-1 away to Nacional.
Julen Lopetegui's men took a quick lead in the sixth minute as Ivan Marcano cleverly flicked a low corner towards goal, giving Rui Silva in between the sticks for Nacional no chance of stopping the strike.
Nacional equalised two minutes later as Willyan connected with a corner and his header took a slight deflection that helped keep it inside the posts.
The away side went back in front after a cross fell to the feet of Hector Herrera, whose shot was well-saved but Yacine Brahimi was there at the back post to tuck away the easiest of chances.
The game was stopped several times in the second half due to issues in the crowd, including flares obscuring vision on the pitch, forcing the players to head into the dressing rooms on the third occasion.
The win lifts Porto above Sporting Lisbon into top spot in the league, with their rivals playing later this evening, while Nacional remain 12th.
