Neil Warnock has left Cardiff City after three years in charge.
He was in the final year of a three-year deal and had already said that he would not continue beyond the end of this season.
The 70-year-old was appointed in October 2016 and guided the club to promotion to the Premier League in 2017-18.
However, they were relegated after just a single season in the top flight. It was Warnock’s eighth promotion as a manager which is a record in the English league.
"I am leaving my beloved Bluebirds after over three years of which have been some of the best days in my long football career," he commented.
"It is a shared belief that this is the right time for a new voice as we believe this squad of players is more than capable of getting success."
The club say an announcement on Warnock’s successor will be made in due course, with chairman Mehmet Dalman adding: "On behalf of Cardiff City Football Club, I thank Neil for his invaluable contribution to the future of this great club.
"He not only gained promotion but played a pivotal role in uniting the fans and the club. I am personally upset by his departure and wish him the very best for the future."
Warnock praised Dalman for his support during his time in charge.
"I would especially like to thank Mehmet Dalman whom I have said many times has been one of the best chairman I have had the privilege to work for," he said.
"His support has been immense, especially in 2019 which for many reasons both on and off the field has been the most challenging period both emotionally and physically that I have ever encountered."
