Porto clinched their 19th Portuguese league title by hammering lowly Santa Clara 5-0 at home.
Porto have a 14 lead on their nearest challengers Benfica with four games remaining.
Porto remain on course for a treble as they face Celtic in the UEFA Cup final in Seville on May 21, and play Uniao Leiria in the Portuguese Cup final on June 15.
Porto coach Jose Mourinho had to watch the game from the stands as he was sent off during last week’s league match gainst Academica.
“The foundations of our success were in the daily work we did to win the championship,’ said Mourinho’s assistant Antonio Andre.
‘ It’s all down to Jose, who is a born trainer.”
“He’s a man who works 24 hours a day for football, for Porto and who is absolutely dedicated to football and lives for it, and that says it all for all this praise, this championship and what we are winning this season,” he added.
