Even though on-loan keeper Joel Robles has impressed fellow Spaniard Roberto Martinez, he will return to Atletico Madrid at the end of the season.
So the manager will not want to risk unsettling Al Habsi too much, especially if he wants to hold on to him if Wigan are relegated.
The keeper told The Sun: “Of course it’s up to the manager, but there will be a lot of people who will be very disappointed if I don’t play — including me, of course.
“I have had to find tickets for more than 90 people. And the number is still growing!
“The club did not take up the full allocation of tickets for the semi–final.
“I have been buying so many that people have been asking me whether I was trying to make sure the same thing did not happen again.
“It will be mostly members of my family, but also plenty of friends including ones I made when I worked as a fireman at the main airport in Oman.
“That was before I got the chance to become the first footballer from the Middle East to play in the Premier League.”
