Crystal Palace have sacked manager Patrick Vieira after a run of one win in 14 Premier League games.
The Eagles are just three points above the relegation zone.
Palace chairman Steve Parish told the club website: “It is with enormous regret that this difficult decision has been made.
“Ultimately, results in recent months have placed us in a precarious league position and we felt a change is necessary to give us the best chance of retaining Premier League status.
“That said, Patrick’s impact since joining us in the summer of 2021 has been significant, and he is held in the highest regard by myself, and all of his colleagues.
“He led the team to a Wembley FA Cup semi-final and respectable 12th-placed finish last season playing some exciting football, which was a challenging and crucial campaign for the club given the changes we made to the squad prior to his arrival.”
Three members of Vieira’s coaching staff – Osian Roberts, Kristian Wilson and Said Aigoun – have also left Selhurst Park.
Paris added: “Patrick has given his all to the club, and we all thank him and his team for their service.
“We also wish Patrick, Osian, Kristian and Said the very best for their futures.”
Palace say the process to appoint a new manager is under way and they will provide an update in due course. Dean Kiely will remain as goalkeeping coach.
