Al Ain, last season’s AFC Champions League™ winners, came into the tie with only a point to show after three rounds and were left stunned as early as the fifth minute when Talisca capitalised on open space at the top of the area to drill a low shot past keeper Khalid Eisa.

The visitors were let off the hook in the 11th minute after Otavio sent Ronaldo through on the counter-attack, but the Portuguese star’s shot went just wide of the left post.

Al Ain lacked spark up front but had a half chance in the 14th minute with Soufiane Rahimi setting up Kodjo Laba, whose tame effort was easily saved by Al Nassr keeper Bento.

At the other end, Eiisa was put to the test in the 24th minute when Angelo forced a fine save from the Emirati custodian who then had to come to Al Ain’s rescue again in the 31st minute when he palmed away Sadio Mane’s shot, only for the ball to fall kindly for Ronaldo to thump in the rebound.

Al Ain were caught napping in the 38th minute when a clever  exchange between Mane and Angelo opened up space for Angelo to slip through the left with his shot taking a deflection off Cardoso, with the ball looping over Eisa and into the back of the net.

Al Ain started the second half brighter and pulled one back in the 56th minute after Park Yong-woo’s shot from distance saw the ball strike the left post before hitting Bento’s back and settling in the back of the net.

Al Nassr came close to furthering their advantage in the 65th minute, but Eisa produced another  brilliant save to keep out Talisca.

Substitute Wesley netted the fourth for Al Nassr in the 81st minute after finishing off Angelo’s pass with a curling effort, before Talisca completed the comprehensive win with a solo effort in stoppage time.

Al Nassr will next travel to Al Khor to face Qatar’s Al Gharafa, while Al Ain play Al Ahli Saudi FC.
