Ahmed Musa has been crowned champion in only his first season in Saudi Arabia after Al Nassr won their final game of the campaign against Al Batin.
Al Nassr beat relegated Al Batin 2-1 in front of their fans to finish on 70 points from 30 matches, a point ahead of closest rivals Al Hilal.
The championship means Al Nassr will represent Saudi Arabia in next season’s AFC Champions League.
This is only their third championship title after they also topped the league in 2013/2014 and 2014/2015 seasons.
The 26-year-old Ahmed Musa scored seven goals in 24 matches for Al Nassr.
He has previously been champion in Russia with CSKA Moscow
