Leeds United chairman Andrea Radrizzani revealed that the club could announce a new manager within hours.
The Elland Road stadium club sacked American head coach Jesse Marsch on Monday.
While assistants Michael Skubala, Paco Gallardo and Chris Armas will take charge of the away Premier League game at Manchester United, Leeds could have a new manager when they take on the same opponent at home in the league at the weekend.
Taking to social media, Radrizzani wrote: "We are on it [finding a new manager].hopefully white smoke by tonight or tmw [tomorrow, Wednesday] morning."
Sources in England and Spain have suggested Rayo Vallecano coach Andoni Iraola is the favorite for the job.
