Al Nassr's Jhon Durán scored twice and Cristiano Ronaldo added a penalty as the Saudi Pro League side booked their place in the last eight of the Asian Champions League Elite with a 3-0 win over Iran's Esteghlal in Riyadh on Monday.

Al Nassr's victory in Riyadh, which followed a 0-0 first-leg draw in Tehran last week, takes Stefano Pioli's side into the quarter-finals of the centralised tournament in Jeddah from 25 April to 3 May.

Duran gave Al Nassr the lead on nine minutes, the Colombian lifting the ball over Seyed Hossein Hosseini after the Esteghlal goalkeeper had given the striker possession 25 yards from goal.

The Saudis doubled their lead from the penalty spot, Ronaldo stepping up in the 27th minute to confidently slot home after Mohammad Niknaf's mistimed challenge on Sadio Mané.

Esteghlal's task was made all but impossible when Mehran Ahmadi was sent off for a second bookable offence late in the first half after he punched Mohammed Al Fatil in the face with his flailing arm.

Duran grabbed his second of the game six minutes from time when he curled a low shot into the bottom corner after Al Nassr had hit the post.

"I think we played well," said Mané. "We created many chances and we scored three goals. I think we got our reward.

"We pressed well together, we pushed them and they made mistakes and from that we scored three goals. We have a clean sheet and we cannot expect more than this."
