Pacos de Ferreira forward Bruno Moreira scored twice to earn his side a 3-1 win at home against Nacional.
Moreira opened the scoring on 18 minutes but Nacional drew level just eight minutes later, with the goalscorer putting the ball past his own goalkeeper.
Pele put his side back in front from the penalty spot before Moreira made up for his earlier mistake to put another into the right goal to make it three.
The win sees Ferreira rise to seventh in the Portuguese Primeira Liga, while Nacional remain in 12th.
