Porto secured a routine 3-0 win over Vitoria Guimaraes in its Primeira Liga opener on Saturday, with Iker Casillas making his debut.
Iker Casillas kept a clean sheet on his competitive Porto debut as Julen Lopetegui's side got its Primeira Liga season up and running with a routine 3-0 victory over Vitoria Guimaraes.
Casillas swapped Real Madrid for Porto in the offseason and watched on untroubled for much of Saturday's match at the Estadio Do Dragao.
Vincent Aboubakar opened the scoring after just eight minutes, and it looked like the visitors were in for a long night as Cristian Tello went close to a second midway through the first half.
