The odds were against Al Ahli goalkeeper, Edouard Mendy, who could not stop Cristiano Ronaldo scoring Al Nassr's opener through a cloud of thick green smoke in the fourth minute of his side's 3-4 defeat to the hosts on Friday.
Cristiano Ronaldo scored a brace, taking his tally to nine goals since the start of the season as he remains the league's top scorer.
This win sees Al Nassr remain in fifth place on 15 points, three behind leaders Al Ittihad.
Al Hilal's Riyad Mahrez scored one goal and assisted another in Friday's match.
