Al Nassr had not lost any of their five league games since Ronaldo's debut on 4 February , drawing his first match before racking up four successive wins.

But that run came to an end against its title rival at the King Abdullah Sports City in Jeddah.

Romarinho got the only goal of the game in the 80th minute, rounding off a devastating counter-attack.

The forward brilliantly brought down Ahmed Sharahili's right-wing delivery on the edge of the box, his first touch taking a defender out of the game before a cool finish sparked jubilant celebrations.

Al Nassr coach Rudi Garcia tried to focus on the positives, however.

"We are disappointed because we did not deserve to lose," he said

"Al Ittihad scored a goal the way they like, on the counter-attack. The league is still long. We are now behind Al Ittihad by a point.

"I am happy with my team. We played in a difficult stadium in front of a strong audience, and yet we played with a wonderful personality."
