Cristiano Ronaldo failed to score in his first appearance in the Saudi Pro League but led Al Nassr back to the top of the table.
Following a suspension, Ronaldo made his Al Nassr debut on Sunday against Al Ittifaq, captaining his new side.
The first match of his highly lucrative contract in Saudi Arabia ended in a 1-0 victory, but Ronaldo was not the goal hero.
Talisca, the Brazilian former Benfica and Besiktas forward, headed the only goal before celebrating with the new boy.
Ronaldo appeared to be sporting a black eye, having received a blow to the face in a challenge with Keylor Navas during this week's exhibition between a Riyadh All-Stars team and Paris Saint-Germain.
Victory in Ronaldo's bow ensured Al Nassr finished the weekend ahead of Al Hilal, having been briefly knocked off top spot by their rivals earlier on Sunday.
