Manager Paul Lambert has left relegated Stoke City four months after joining the club to replace Mark Hughes.
“Whilst he was unable to guide us to safety, it certainly wasn’t due to a lack of effort, professionalism and dedication,” a Stoke statement said.
The Potters added that they plan to name a new boss “as soon as possible”.
Last week, the club’s owners said they would continue to give managers time “to prove themselves”.
However, the departure of the ex-Aston Villa and Norwich boss leaves Stoke looking for a third manager in a year.
“The club would like to thank Paul for his work over the past four months and wish him well for the future,” the club statement said.
“Paul would like to thank the board, players and staff for the opportunity and their support. He would also like to thank the fans for their unwavering support. Whilst looking forward to his next challenge, he would like to wish the club every success next season.”
