Benfica routed Vitoria de Guimaraes 5-0 to win a club-record fourth straight Portuguese league title on Saturday.
Benfica lifted the trophy with one round to go by opening an eight-point lead over FC Porto, who host Pacos Ferreira on Sunday and can only get within two points of their rivals if they win both of their remaining matches.
It is the 36th league title for Benfica, who led the league since the fifth week, nine more than Porto's 27.
Benfica cruised to victory after Franco Servi and Raul Jimenez scored less than 20 minutes into the game at the Stadium of Light. Pizzi added to the lead before half-time and Jonas netted twice in the second half to seal the victory and the title celebration in front of the home fans.
Benfica hadn't lost at home against Vitoria de Guimaraes since 2009, winning seven in a row.
Porto were the last team to win four consecutive titles, from 2006-09. They also won five in a row, from 1995-99. The last time Benfica won three in a row was from 1975-77.
