Former England manager Roy Hodgson has been reappointed as Crystal Palace boss until the end of the season.
Patrick Vieira, who replaced Hodgson at Selhurst Park in July 2021, was sacked by Palace on Friday after a 12-match winless run in all competitions.
Hodgson, 75, managed Watford from January to May 2022, leaving after they were relegated to the Championship.
"It is a privilege to be asked to return to the club, which has always meant so much to me," said Hodgson.
"Our sole objective now is to start winning matches, and to get the points necessary to ensure our Premier League status."
Hodgson had said he did not expect to take another managerial job in the Premier League after his departure from Watford.

Ray Lewington also returns to Palace as first-team coach with Paddy McCarthy, who took charge of Sunday's 4-1 defeat at Arsenal, named assistant manager.
"I would like to welcome Roy and Ray back to the club," said Palace chairman Steve Parish.
"We are obviously in a very challenging period but we believe that Roy's and Ray's experience, knowledge of the club and players, alongside Paddy can help fulfil the immediate requirement of keeping us in the league."
Palace are 12th in the top flight but only three points above the relegation zone following their defeat at Emirates Stadium.
Hodgson's first game in charge during his second spell will be at home to Leicester on 1 April.
His managerial career has spanned more than 45 years and includes stints at Inter Milan, Blackburn, Fulham, Liverpool, West Brom and Palace, while he has also led the national sides of Switzerland, United Arab Emirates and Finland.
Hodgson has managed six clubs in the Premier League, taking charge of 382 games and already holds the record for being the competition's oldest manager.
He led England from 2012 to 2016, but they failed to qualify from their group at the 2014 World Cup and Hodgson resigned after a shock 2-1 defeat by Iceland in the last 16 of Euro 2016.
In May 2022 he was honoured with a CBE for his services to football.
