Crystal Palace have sacked manager Patrick Vieira after a 12-match winless run.
Palace have not won a match in 2023 and were beaten 1-0 by Brighton in the Premier League on Wednesday, their third defeat in a row.
They are 12th in the table but are only three points above 18th-placed Bournemouth, who have a game in hand.
“It is with enormous regret that this difficult decision has been made,” chairman Steve Parish said.
“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.”
Under-21s boss Paddy McCarthy will take charge for Sunday’s visit to leaders Arsenal on Sunday (14:00 GMT) after he led training on Friday morning.
“Obviously it’s a massive moment for myself, but ultimately it’s not about me,” said McCarthy, who will work alongside U21s assistant Darren Powell.
“I’ll push all of that emotion to one side. Yes, it’s going to be a great opportunity for myself and Darren to manage at that level, but the focus is solely on setting the gameplan and implementing that on Sunday.”
Frenchman Vieira, 46, was appointed before the start of the 2021-22 season and led the Eagles to a 12th-placed finish, earning praise for an attacking style.
However, this season they have scored just 21 goals in 27 games – only Wolves, Everton and bottom-of-the-table Southampton have fewer.
Before their defeat by Brighton, Palace had gone three consecutive games without a shot on target.
No Premier League team has won fewer points in 2023 than Palace, who have taken five from a possible 33.
Three members of Vieira’s coaching staff – Osian Roberts, Kristian Wilson and Said Aigoun – have also left the club and the process of appointing a new manager is under way.
Just five points separate the Premier League’s bottom nine clubs heading into the final months of the season.
Their final 10 games of the season will see them face all eight of their relegation rivals.
Parish added: “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.
“Patrick has given his all to the club, and we all thank him and his team for their service.”
Vieira’s departure means there are no black managers in charge of a club in the top flight of men’s and women’s football in England.
Newcastle United striker Callum Wilson said this week he believes some black footballers in England may be put off going into management by their experiences of racism as players.
In the wider Premier League, only six managers have been in charge for more than three years and nine have been in charge for fewer than 12 months. The league average stands at two years and five days.
There have been nine managerial sackings during the 2022-23 campaign – one fewer than last season’s total, which equalled the Premier League record.
Vincent Kompany, whose Burnley side lead the Championship by 13 points and play Manchester City in the FA Cup quarter-finals on Saturday, has questioned the decision to sack Vieira.
“It doesn’t sit well with me because if someone is underachieving in comparison to the resources you have then I think it is fair enough that a club makes a decision,” the 36-year-old said.
“But I think if you are overachieving, which is what they are doing, then I think whoever is making the decision has got to come forward and say ‘I made the decision because I think at the end of the season we are going to be safe because of that decision’.
“What you have done is taken out a manager who is overachieving, no matter which way you want to turn it. I think that is a problem in general in football.”
