All three of Porto's Mexican imports were involved in goals Sunday, while Vincent Aboubakar added two goals in a romp.
Hector Herrera and Jesus Corona scored while Miguel Layun had an assist as the trio of Mexican internationals led Porto to a 5-0 victory over Boavista.
Sunday's match was the first Liga NOS game for Porto since the club fired head coach Julen Lopetegui after a defeat to rival Sporting and home draw with Rio Ave. Former coach Rui Barros was on the bench as the interim manager for the victory.
Corona extended the lead in the 62nd minute.
