Saudi Arabia has three representatives in the AFC Champions League final eight after Al Zaa'em made light work of their UAE opponents in their Czech boss' final game in charge
Hasek's side made ensured all three Saudi Arabian clubs remaining in Asian competition progressed to the final eight, with a comfortable victory over the beleaguered UAE side.
“The team had a superb performance tonight," Hasek told reporters after the game. "They are heroes and they had a great performance coupled with a big win which they deserved and they enjoyed their performance in the game."
The Czech boss added that he would now leave the Riyadh club whom he joined in January after Thomas Doll's dismissal.
“When I came to Al Hilal, I had a specific target and now I have achieved what I came here for," he said.
“It was a good experience with Al Hilal and as my contract has ended with them now, I wish them all the best and I will look for the best offers for me.”
Bani Yas boss Gabriel Calderon admitted he never expected such a heavy defeat.
“It is a heavy defeat and honestly we didn't expect it," he told reporters on his return to his former club.
"We tried our best to make a good comeback but unfortunately Al Hilal were at their best and they managed to score more goals."
However, Calderon was proud of his side's achievement in reaching the final 16.
“I previously said that getting to this stage was a great achievement and we tried our best to continue in the competition, but we faced strong opponents," he said.
Meanwhile, Bani Yas first-team director Fareed Ali blamed a lack of support from the club's board of directors for the humiliating defeat.
“No one from the board of directors attended the match,” he said. “We need moral support, the players need moral support.
"There were some mistakes from the players but this was again because there was no moral support.”
