The Portuguese forward struck in the 81st minute of what had been a frustrating game overall for the Riyadh club.
Al-Nassr were dominant from start to finish against a stubborn Al-Fayha defence. The away side enjoyed more possession and were the only team creating any danger – the hosts did not have a single shot until very late in the game and it missed the target.
Ronaldo had the first big chance right before half-time when he chested down inside the Al-Fayha box and hit a shot, but it was saved by the goalkeeper. Aymeric Laporte had another opportunity shortly afterwards, but his effort from close range missed the target.
Al-Nassr pushed on in search of the opening goal in the second period but struggled to break through the home team’s defence. One promising attack on the hour mark saw Ronaldo drive into the box but his effort was blocked. Anderson Talisca was the next star to come close to breaking the deadlock when he got onto the end of a pass, but his shot went wide of the mark.
Finally, Ronaldo popped up with the vital moment when he combined with Marcelo Brozovic and bobbled the ball into the net to secure the victory for his team.
