Porto bounced back from last weekend's 1-1 draw with Maritimo by beating Estoril Praia 2-0 at the Estadio do Dragao tonight.
The clash was only six minutes old when the hosts edged ahead, with Vincent Aboubakar firing past Pawel Kieszek to open the scoring.
Summer signing Iker Casillas was called into action on 32 minutes when the veteran put his experience to good use by denying Leandro Chaparro and preserve a slender lead at the break.
The Real Madrid legend pulled off another smart save early in the second half as Estoril slowly but surely grew into the clash.
However, Julen Lopetegui's side effectively wrapped up the three points on 62 minutes when Maicon's long-range drive left Kieszek with no chance.
