Swansea City have sacked manager Paul Clement with the club bottom of the Premier League, having won just three times this season.
Clement, 45, took charge in January with Swansea in the relegation zone and guided them to a 15th-place finish.
Chairman Huw Jenkins said that changing the manager halfway through a season “was the last thing we wanted to do”.
He said: “We felt we couldn’t leave it any longer and needed to make a change to give the best chance of an uplift.”
Swansea announced that assistant managers Nigel Gibbs and Karl Halabi have also left the club.
The Welsh club says it will give a further update on replacement coaching staff “within the next 24 hours”.
Before joining Swansea, Clement had worked as Carlo Ancelotti’s assistant manager at Chelsea, Paris St-Germain and Real Madrid.
He had one, short-lived managerial stint at Derby County which ended in 2016 and he was then reunited with Ancelotti at Bayern Munich.
Clement joined Swansea on a two-and-a-half-year deal in January, becoming the club’s third boss of the 2016-17 season following the departures of Bob Bradley and Francesco Guidolin.
“We had three different manager last season and as a result we all wanted to give Paul as much time as possible to turn things around,” Jenkins added.
“Paul has been at the club for 12 months and what he achieved in the second half of last season to keep us in the top flight was a tremendous feat.
“For that, and his effort and commitment this season, it goes without saying that the club thanks him for his work, together with Nigel and Karl.”
The Swans were bottom of the table when Clement took charge but he oversaw a remarkable escape from relegation after a strong end to the campaign.
However, a summer of poor dealings in the transfer market sowed the seeds for a dreadful start to the current term.
Last season’s leading scorer Fernando Llorente and player of the year Gylfi Sigurdsson were sold but not adequately replaced.
