Cristiano Ronaldo scored Al-Nassr’s second goal as the Saudi Pro League champions overcame an hour-long security delay to beat Uzbekistan’s Neftchi 3-1 in the AFC Champions League Elite on Monday.

Kick-off was delayed after Saudi Arabia’s Civil Defence issued a safety warning 15 minutes before the scheduled start time in Riyadh, which has been targeted by missiles fired from Yemen-based Houthis in recent days.

Ange Postecoglou’s side shook off the interruption to go in front through Angelo in the 33rd minute with a deflected strike before Ronaldo doubled the lead nine minutes later.

The 41-year-old struck after Sadio Mane delivered a looping cross from the left that Aiman Yahya directed into Ronaldo’s path with his chest, and the Portuguese forward lashed the ball into the bottom corner with a shot on the turn.

Alisher Odilov pulled one back for Neftchi six minutes into the second half, but Ikromjon Alibaev’s red card for a foul on Mohamed Simakan in the 65th minute and an own goal by Anvarjon Gofurov 13 minutes later sealed the win for Al-Nassr.

Meanwhile, defending champions Al-Ahli scored twice in the second half to pick up their first win of the new campaign as Marino Pusic’s side beat Al-Wasl from the United Arab Emirates 3-1.

Roger Ibanez put Al-Ahli ahead with a 20th-minute header but Pedro Malheiro levelled in the third minute of first-half stoppage time.

Goals from Trincao and Feras Al-Brikan in the 58th and 91st minutes, respectively, moved Al-Ahli onto four points from their opening two matches.

“We created also in the first half, but in the second half we made our goals, and I think that was the difference,” said Trincao. “Physically we were a little bit better, and that was the key to changing the game.”

Houssine Rahimi scored twice as Al-Ain defeated Air Force Club 4-1 in Basra, while Hossein Goudarzi’s 60th minute goal earned Iran’s Esteghlal a 2-1 win over Al-Gharafa.

A last-minute penalty from Dostonbek Khamdamov salvaged a 1-1 draw for Pakhtakor against Brendan Rodgers’ Al-Qadsiah in Tashkent, while Tractor from Iran were held to a 0-0 draw by Qatar’s Al-Shamal.

The top eight finishers in the 16-team league phase in both East and West Asia will progress to the knockout rounds.
