Leeds United have confirmed the departure of head coach Jesse Marsch.
The announcement came after a 1-0 defeat by Nottingham Forest left the club out of the relegation zone on goal difference only.
Michael Skubala, Paco Gallardo and Chris Armas will take charge of Wednesday's match at Manchester United.
A club statement said: "We would like to thank Jesse and his backroom staff for their efforts and wish them well for the future.
"The process of appointing a new head coach is under way and we will continue to keep supporters up to date throughout the coming days."
Leeds made a good start to this campaign, with two victories from the opening three matches.
But the team's form took a dip and only two more wins were secured from the next 17 league matches, to leave them in 17th place on 18 points after 20 matches.
Leeds, who recruited four new players in the January transfer window, including Marsch's fellow American Weston McKennie, follow Wednesday's match at Old Trafford when they face Man Utd again on Sunday.
