The rout in Riyadh at the Prince Faisal bin Fahd stadium came 12 months after Baniyas coach Gabriel Calderon had guided Al Hilal to the same stage of the competition. This time the Argentinian was on the receiving end of a drubbing that was orchestrated by Yoo, who opened the scoring in the 23rd minute. The 24-year-old international then followed up that effort with goals in the 38th, 52nd and 61st minutes.
Former Bolton midfielder Christian Wilhelmsson contributed with a goal in either half, while Mohammad Salem also got in on the act near the death. Baniyas, who played the last minute a man down after Saleh Al Menhali was sent off, avoided a leaving goalless when they were awarded a 57th minute penalty converted by Francisco Yeste.
Al Ittihad progress
In Wednesday's other game, another Saudi side, Al Ittihad, progressed with a 3-0 defeat of Iranian outfit Piroozi Athletic. Naif Hazazi put the hosts into a 35th-minute lead from the spot with Abdelghani Faouzi doubling up on the stroke of half-time and Abdoh Autef completing the lopsided scoreline two minutes from time.
On Tuesday, former Australia captain Lucas Neill missed a penalty in a dramatic penalty shoot-out that saw his Emirati Al-Jazira club crash out to Al-Ahli also of Saudi Arabia. The game had finished 3-3 after extra time with Al-Ahli prevailing 4-2 on penalties. In Tuesday's other action, Iranian champions Foolad Sepahan beat close domestic rivals Esteghlal 2-0.
