Ronaldo moved to Al-Nassr on a lucrative deal last January and scored eight goals in his first five games but he has been unable to sustain that pace.

In Al-Nassr's first game since the departure of coach Rudi Garcia, Ronaldo drew a blank while Ighalo, who had a loan spell at Manchester United in 2020, scored twice to hand Asian champions Al-Hilal the win.

Ronaldo was yellow carded in the 57th minute after he tangled with Gustavo Cuellar and things only got worse from there.

The Portugal striker had a goal disallowed for offside in the 77th minute and after he was awarded a penalty six minutes later the Video Assistant Referee reversed the decision.

Ronaldo was later taunted as he left the field with Al-Hilal fans waving Lionel Messi shirts.

Al-Nassr interim coach Dinko Jelicic told reporters the game changed when they conceded the first spot kick.

"The first penalty kick broke us, it was influential in the course of the match," he said.

"Al-Hilal were better than us in some periods. My team showed good glimpses and could pave the way for the next weeks."

Al-Nassr are three points behind leaders Al-Ittihad, who have played a game less.
