Swansea will not be extending the contract of manager Carlos Carvalhal, the club have announced.
The Swans were relegated from the Premier League on Sunday, the end of their seven-year stay in the top flight confirmed by a 2-1 home defeat to Stoke.
Carvalhal was appointed as Paul Clement's successor in December, just three days after leaving Sheffield Wednesday.
Carvalhal won five of his first nine league games as Swansea climbed to 13th place, but they were condemned to the Championship after picking up only three points from the last 27 on offer.
Managers already being linked with the post include former Wales boss Chris Coleman, recently sacked by Sunderland, and Swedish club Ostersund boss Graham Potter.
Carvalhal said after the Stoke game that Swansea's American owners had spoken to him about being in charge next season.
But Swansea have decided not to take up the option of extending the Portuguese's short-term contract.
Carvalhal has thanked the club and supporters for their support during his tenure.
First-team coaches Joao Mario and Bruno Lage have also left the Liberty Stadium along with match analysts Jhony Conceicao and Paulo Sampaio.
