Al Nassr captured the Saudi Pro League title on Thursday with a commanding 4-1 win over Damac at Al-Awwal Park.
The victory ended a seven-year league drought for the club and delivered the first major trophy since Cristiano Ronaldo joined the squad four years ago.
Championship Decider
Manager Jorge Jesus's team finished the domestic campaign with 28 wins and 86 points, two points ahead of runners-up Al Hilal.
Al Nassr also led the league in scoring with 91 goals.
The host side opened the scoring in the 34th minute when Sadio Mané headed in a corner kick from João Félix.
Kingsley Coman doubled the lead in the 52nd minute with a left-footed strike from the edge of the box.
Damac pulled one back through a penalty, but Ronaldo restored the two-goal cushion with a free kick into the far corner.
He added his second of the match in the 81st minute to seal the win.
The title comes after consecutive runner-up finishes in Ronaldo's first two seasons and a third-place finish last season.
