Hilal, two-time winners of the ACL, hammered Gabriel Calderon's side 7-1 with an accomplished attacking display last night at the Prince Faisal bin Fahd stadium in Riyadh.
The game was already well beyond the UAE side by the time Saleh Al Menhali was given his marching orders in the 89th minute for a second bookable offence after fouling a Hilal player.
Yoo Byung-soo, the Saudi club's diminutive South Korean forward, was on target four times, and Christian Wilhelmsson, who had a hand in five of those goals, scored twice. Mohammed Salem rounded off with a seventh four minutes from time.
Francisco Yeste, who came on as a second-half substitute, scored a consolation from the penalty spot on 57 minutes.
Yoo scored his first on 23 minutes as he reacted quickest to Wilhelmsson's blocked shot. Wilhelmsson, the Sweden international midfielder, doubled the lead three minutes later, finishing off asuperb move.
A second for yoo just before half time was followed up by a third on 53 minutes for his hat-trick. Wilhelmsson made it four as his shot was deflected in off Ismael Bouzid, the Baniyas defender, to extend Hilal's lead.
Yoo scored his fourth of the game just past the hour and set up substitute Salem to complete the rout.
In last night's other last-16 tie, Saudi Arabia's Al Ittihad beat Iran's Persepolis 3-0 to advance to the final eight.
