Amid growing speculation on social media about Cristiano Ronaldo's presence in Iran for Al Nassr's AFC Champions League clash against Esteghlal, head coach Stefano Pioli addressed whether the Portuguese star will be available for the match.

Al Nassr, one of three Saudi Arabian sides to dominate the west region's group stage, needed only nine minutes to take the lead in Riyadh.

Al-Nassr's Jhon Duran scored twice and Cristiano Ronaldo netted a penalty as the Saudi Pro League side booked a place in the Asian Champions League Elite last eight on Monday with a 3-0 win over Iran's Esteghlal while Qatar's Al-Sadd beat Al-Wasl.

Cristiano Ronaldo might have recently turned 40 but he is showing no signs of slowing down as the Portuguese great converted a penalty to help Al Nassr sail into the quarter-finals of the AFC Champions League Elite.

Ronaldo, the Al Nassr captain, was reportedly rested for last week's goalless draw in the first leg in Iran, however returned to lead the side at Al Awwal Park.
