Al Qadsiah settled the quicker and produced a couple of early efforts through Mohammed Al Qahtani’s and Tijjani Reijnders’ header but neither were on target.

The Dutch midfielder then created space for himself in the 24th minute, shifting away from several defenders on the edge of the box only to send his strike straight at Al Wasl custodian Dinko Horkas.

The visitors looked sluggish and on the one occasion they were able to string a couple of passes, Mehdi Taremi and Nicolas Gimenez initially combined well before one too many passes saw the move fizzle out.

Brendan Rodgers sent on Italian forward Retegui for the second half as his Al Qadsiah side continued to ask questions of Al Wasl’s defence.

Reijnders was sent through into the box by Retegui in the 51st but was quickly closed down by Ridwan Popoola before Quinones sent a header sailing over the bar.

Quinones did much better with his second header six minutes later, rising highest at the back post to thump home Christopher Baah’s cross to give Al Qadsiah their first-ever goal in the competition.

The Saudi Pro League side kept the pressure on and found their second a minute after the hour mark, Retegui tapping in from close range after good work from Al Qahtani on the right.

Al Wasl pulled a goal back through Leandro Spadacio in stoppage time but it came too late to change the final result.

Al Qadsiah will go to Uzbekistan to face Pakhtakor on Matchday Two while Al Wasl will look to bounce back when they host defending champions Al Ahli Saudi FC, with both matches to be played on October 12.
