Leeds have announced that they have parted company with manager Brian McDermott by mutual consent.
The former Reading boss took charge at Leeds in April 2013, signing a three-year contract, but his future at Elland Road has looked increasingly uncertain since Massimo Cellino's takeover of the West Yorkshire club earlier this year.
Although the takeover was still being finalised at that stage, McDermott was apparently sacked at the end of January, and assistant Nigel Gibbs took charge of the side for a 5-1 win over Huddersfield.
However, Leeds released a statement after the game saying McDermott had not been fired and he returned a few days later, saying he had been re-instated.
But he will now depart after guiding the club to 15th place in the recently-concluded Championship season.
Leeds owner Massimo Cellino told the club's official website: "Brian is a great manager and a great guy. He has been unfortunate to work in such difficult circumstances.
"I did not fully understand the mess he had to work in, and the broken promises he had to deal with, until I have got involved trying to turn Leeds around.
"He has been a gentleman to deal with in our discussions and has been very understanding of my wish to implement a new structure.
"His main concern and priority at all times has been the welfare and protection of Leeds United.
"I wish him well for the future, where I am sure he will continue to have more success, and thank him for his efforts in being a stabilising and unifying figure behind the scenes in very difficult circumstances.
"His honest efforts to guide us to the safety of mid-table when faced with many difficulties is appreciated by us all. He will always be a friend of Leeds United."
McDermott added: "It has been my great privilege to manage this great club and I have enjoyed the challenge immensely.
"However, it is clear that Massimo wishes to implement a new structure and feels he will work more successfully for Leeds with a coach rather than a manager.
"I respect that Massimo must be fully supported in putting together his vision for the club, so he can bring us the success we all want.
"It is my belief that when truly United we are stronger. Massimo wants to bring a new energy to the club so that we can return to where we belong as a healthy football club.
"To my players for their efforts I say a big thank-you. To all the staff and, especially, my great assistant manager Nigel Gibbs and my great friend Patrick Dolan, I am especially grateful for their support.
"Finally, to the incredible force that is the Leeds United supporters, I offer my heartfelt thanks.
"Your support of me and the players was always an inspiration and I urge everyone to get behind the team and the new owner next season, to get us back to where we need to be, fighting for trophies and competing at the top-table of English and European football.
"It won't be easy, but Marching On Together we can get there.
"I wish Massimo and all my friends at Elland Road every success in the future."
