The Whites parted with Jesse Marsch on Monday and had aimed to bring in a replacement before the weekend.
Orta’s role is being scrutinised as Leeds have to stay up for 49ers Enterprises’ proposed full takeover to go through.
Relegation could affect the Americans’ plans for the buyout. Andrea Radrizzani remains the majority owner, with a 56% stake in the Elland Road club.
The 49ers own the remaining 44% and are keen to buy the Italian businessman’s stake.
Orta knows he has to get the next managerial appointment right.
The owners were said to be open to sacking Marsch earlier in the campaign after the woeful results. However, Orta insisted Leeds hold their horses which resulted in a relegation scare.
A deal for Corberan was also there to be done before West Brom extended the Spaniard’s deal.
Radrizzani would have been open to having the former Leeds assistant manager back at the club. However, Orta wanted to explore alternative options before moving for Corberan.
It proved costly as the Baggies quickly handed him a new deal amid the rumours.
The west Yorkshire club have been recently linked with Nuno Espirito Santo and River Plate manager Marcelo Gallardo.
Other names could still emerge, but the onus is on Orta to bring in a manager that can keep Leeds up.
