Pierre-Emerick Aubameyang hit the winner as Al-Qadsiah inflicted a 2-1 defeat on Al-Nassr in the Saudi Pro League on Friday to end their 21-match unbeaten run. 

Cristiano Ronaldo's seventh league goal of the season put Al-Nassr ahead, but Al-Qadsiah replied swiftly through Julian Quinones before Aubameyang struck the decisive blow.

The hosts drew first blood in the 32nd minute when Ronaldo slotted home after Al-Qadsiah goalkeeper Koen Casteels had spilled a routine catch from Talisca's cross.

However, Al-Nassr's joy was short-lived when Quinones brought down Turki Al Ammar's delivery five minutes later, with the Mexcio winger firing past Bento to level the scores.

Quinones also played a part in the winning goal after brilliantly turning the ball back across goal from Nahitan Nandez's search pass to tee up a simple finish for Aubameyang. 

The result sees Al-Qadsiah move level on 22 points with third-placed Al-Nassr, with Al-Shabab also level with them.

Stefano Pioli's Al-Nassr are six points adrift of defending champions and leaders Al-Hilal, who also have a game in hand.
