Manager Sam Allardyce has left Leeds United after his four-game tenure ended in relegation from the Premier League.
The 68-year-old lost three and drew one of his matches in charge, having succeeded Javi Gracia on 3 May.
Leeds will return to the Championship after a three-season stay in the top flight.
"It has been an honour to manage Leeds United, a great club with an incredible fan base, who deserve to be in the Premier League," said Allardyce.
"At this stage in my career I am not sure taking on this challenge, which is potentially a long-term project, is something I could commit to, but I wish the club every success for the future and hope the club returns to the Premier League, where they belong."
