Boss Paul Lambert has left Stoke by "mutual consent" following the club's relegation to the Championship.
Lambert was appointed on a two-and-a-half-year deal in January after Mark Hughes was sacked but the former Aston Villa and Norwich boss was unable to keep the club in the Premier League.
The Scot won just two of his 15 games in charge - his first fixture against Huddersfield in January and what proved to be his final match at Swansea last weekend.
A statement on stokecityfc.com read: "The club would like to thank Paul for his work over the past four months and wish him well for the future.
"Whilst he was unable to guide us to Premier League safety after being appointed in January, it certainly wasn't due to a lack of effort, professionalism and dedication on his part."
The statement added: "The club will appoint a replacement as soon as possible in order to give the new manager time to prepare for the challenge of the 2018-19 season in the Championship."

Despite a poor run of results in the Premier League, not many goals and a stadium full of disgruntled fans, Aston Villa's chief executive Tom Fox said on Wednesday manager Paul Lambert had the full support of American owner Randy Lerner.
Villa, who started the season brightly and were second in the middle of September, have slipped to 15th in the table, the same lowly position they ended last season.
Lambert's misfiring side have taken only 12 points from their last 18 league games, but Fox told BBC Sport sacking Lambert mid-season would be like 'flipping a coin'.
When things aren't going well, fans bay for that type of blood. That's not the way that I or the owner are going to make a decision. It's a false narrative.
I think football's a funny business and I think to put it all on the manager, again, that's a bit of a false narrative.
Our focus for the last couple of months has been on making sure we support Paul to make us as successful as possible, and I think we're heading in the right direction.
Aston Villa manager Paul Lambert has hit back at claims from record signing Darren Bent, insisting his decision to let the striker leave on loan was "nothing personal".
The 30-year-old former England international was out of favour at Villa Park this season four years after arriving from Sunderland in a club-record £24million deal, making only eight appearances for the Premier League side - seven of them as a substitute.
Bent was regularly overlooked by Lambert and spent last season on loan at Fulham before he was loaned out to Brighton earlier this term. He then joined up with Championship high-flyers Derby on a season-long loan deal on January 2, theoretically putting an end to his Villa career with his contract due to expire this summer.
I never stood in his way to go to any other club.
The only clubs that came in for him were Championship clubs - not one Premier League club. That says a lot, so it was never personal.
He went to Brighton for a month and [they] never wanted to renew it. He's gone to Derby and never started a game.
At Fulham, he never played a lot of games towards the tail end. Was it personal with me when he was at Fulham? It is what it is, but it was never personal.

Aston Villa manager Paul Lambert is facing pressure to resign from supporters following Monday night's 2-0 defeat at QPR.
The result consigned Villa to an unwanted piece of history, as they became only the ninth club in Premier League history to lose five consecutive matches without scoring a goal.
Lambert's side have now shipped 13 goals without reply in five matches, and supporters have been venting their displeasure on Birmingham Mail's Facebook page.
Richard Hunt wrote "Lambert out, enough is enough," while Mark Pearson suggests Lambert has "had his time. He wasn't good enough."
Villa host Spurs on Sunday before travelling to high-flying West Ham the following weekend, where Liverpool and Man City have already fallen to defeats this season.
Paul Lambert is the new manager of Aston Villa, the Barclays Premier League club have announced.
"The Board of Aston Villa are delighted to confirm that Paul Lambert has been appointed Villa manager," said a statement on the club's website.
