The London club sit just one point above the relegation spot after 17 games, and have taken the option of getting rid of the former Newcastle United boss
Alan Pardew has left his role as manager of Crystal Palace, the club have confirmed.
Pardew left Newcastle United to take over at Selhurst Park in January 2015 and led them to a 10th-place finish in the Premier League.
But his first full season in charge did not prove as successful in the league, Palace enduring a dreadful second half of the campaign as they finished just five points above the relegation zone.
The former Southampton and Charlton Athletic boss led Palace to the FA Cup final, only to see his side beaten 2-1 in extra time as Jesse Lingard scored the winner for Manchester United.
And Pardew has failed to turn around their fortunes in the first half of the 2016-17 season, with Palace just a point above the bottom three with 15 points from 17 games.
Chairman Steve Parish said: “I would like to put on record our sincere gratitude for the tremendous service Alan has given us, both in his time here as manager and previously as a player.
“Following a fantastic second half of 2014-15, the 2015-16 season culminated in only narrowly missing out on winning the FA Cup as well as securing our Premier League place for a record-breaking fourth time.
“During his tenure Alan’s hard work and dedication were without question, he has improved so many areas of the club and we wish him the very best for the future.
“With games now coming thick and fast over the holiday period the club are hoping to put someone in place as quickly as possible but have nothing to say about a replacement at this time.”
