Leeds have sacked manager Jesse Marsch following Sunday’s disappointing 1-0 defeat at Nottingham Forest.
The West Yorkshire outfit are outside the Premier League drop zone on goal difference having failed to win any of their last seven top-flight games.
Their most recent league victory came against Bournemouth on November 5, a run of results which has seen a slide to 17th place in the table.
Marsch, 49, lasted less than 12 months in charge at Elland Road after being appointed as Marcelo Bielsa’s successor in late February 2022.
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.”
Marsch arrived in England having enjoyed previous success at New York Red Bulls, FC Salzburg and RB Leipzig.
The American coach kept the Whites in the Premier League in 2021-22 but his side have struggled to kick on and climb the table this term, despite being backed heavily in the transfer market.
USA internationals Tyler Adams and Brenden Aaronson were recruited last summer, with fellow Stars and Stripes midfielder Weston McKennie added on loan last month.
Club-record signing Georginio Rutter was also purchased, for a reported £36million.
West Brom boss Carlos Corberan — Bielsa’s former assistant at Elland Road — has been earmarked as the early favourite to take the reins.
Leeds will face Manchester United twice in the coming days, first making the trip to Old Trafford on Wednesday night before hosting the Red Devils on Sunday.
