Porto stayed undefeated to grab the seasons' most sought-after domestic trophy with a dramatic comeback in the last few weeks, snatching the title away from arch rivals Benfica, who were four points ahead just three rounds ago.
Argentine playmaker Lucho Gonzalez fired in from the spot after 23 minutes and Colombia's Jackson Martinez extended the lead in the second half to give Porto a third consecutive title.
"This is Porto: quality, persistence and hard work. We won in the key moments," overjoyed Porto coach Vitor Pereira told Portuguese television, shortly before brandishing the league trophy in his hands.
"I am proud and we fully deserved the win."
The climax to one of the most finely balanced Portuguese championships was Porto's stoppage-time win over Benfica at the Dragao stadium a week ago, which put them in command in the title race.
"This sure was one of the hardest championships we have won. A lot of people thought we had lost the title but we never believed that," goal-scorer Gonzalez said.
Instead, it was their rivals Benfica whose season unravelled in the space of a week, after they also suffered a last-gasp defeat at the hands of Chelsea in Wednesday's Europa League final.
