Iker Casillas kept a clean sheet on his competitive Porto debut as Julen Lopetegui s side got their Primeira Liga season up and running with a routine 3-0 victory over Vitoria Guimaraes.
Casillas swapped Real Madrid for Porto in the close-season 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.
Lopetegui had to wait until the hour mark for a two-goal cushion, though, as Aboubakar netted again shortly after Casillas made a good save.
Silvestre Varela then added a third late on for Porto as their bid for a first Primeira Liga title since 2013 got off to a solid start.
