Of that travelling party, only one female from one of the A-League's most passionately supported clubs will be in attendance.

Western Sydney was hoping for a contingent of around 200 of its supporters to spur it on against Al-Hilal at King Fahd Stadium in Riyadh on Sunday morning (AEDT).

However, a club spokesperson said a strict and complex process for obtaining Saudi Arabian visas, along with the travel cost, had reduced the touring party leaving from Sydney to 13 men and one woman.

Under Saudi law, single women must be in the company of their husband or a male family member to secure a visa, and a Wanderers spokesperson confirmed the a solitary female supporter will make the journey with her father.

Another challenge facing fans, members of the media and Wanderers management, has been the Saudi stipulation that people of the Jewish faith, and people with Israeli stamps on their passport, are refused entry to the country.

Western Sydney declined to comment on whether its chairman Paul Lederer, who is Jewish, will travel to Riyadh.

Fairfax media reported earlier this month that the Asian Football Confederation may look to arrange a way for Lederer to attend under conditions usually reserved for diplomats.

AFC Champions League regulations state: "Hosting club and its National Association must guarantee and ensure that access to the stadium will be granted to the AFC delegation, officials and players of the visiting club, sponsors, travelling fans and media without any discrimination of gender, race or nationality."

In the first leg at Parramatta Stadium the "Blue Wave" of Al-Hilal fans filled up the entire southern end of the ground behind the goal.

However in the 65,000-capacity cauldron of King Fahd Stadium, the Wanderers fans will merely be a drop in the ocean as they watch their team attempt to press home their 1-0 advantage.

Veteran goalkeeper Ante Covic explained on Monday how important the Wanderers supporters were to the team's success.

"They're a big part of this club right now," he said. "When you come to a club like this and you look out at the stands ... it lifts us on the field."

When the Wanderers began organising travel packages a month ago, there were initial concerns that female supporters may be segregated in a separate part of the ground.

However, the solitary travelling female fan will be allowed to sit with the 13 other Western Sydney supporters.

Last year Saudi Arabia passed a law permitting women to attend football matches.
