Alan Pardew became the latest manager to leave a role early during the coronavirus pandemic.
Here the PA news agency looks at those who have left their jobs or will miss out on leading their team in major tournaments.
Mick McCarthy
McCarthy was always going to leave in August to make way for Stephen Kenny, the Republic's Under-21 boss. But he was replaced by Kenny with immediate effect following the postponement of the Republic's European Championship play-off with Slovakia. "That's hugely disappointing, but I fully understand it," McCarthy told FAI TV.
Michael O'Neill
O'Neill stepped down from his country to focus on his duties at Stoke, who he joined in January. Initially the 50-year-old was to take charge of Northern Ireland in the European Championship play-off against Bosnia and would have led them to Euro 2020 if they had qualified. But with the tournament pushed back until 2021 because, O'Neill left after eight years in charge.
Phil Neville
The England Women's manager will not renew his contract and will step down next year. The former England international was due to lead Team GB at this summer's Olympic Games before it was pushed back a year. He was also preparing for Euro 2021 in England before that was moved to July 2022 because of the knock-on effect of the coronavirus pandemic.
Age Hareide
Hareide's contract expires this summer and Denmark had already lined up Kasper Hjulmand as his successor. Former Norwich and Manchester City defender Hareide, who also managed Norway, took Denmark to the World Cup in 2018. Hjulmand will now take charge at the rescheduled Euros in 2021.
Graeme Jones
Luton manager Jones was the first notable domestic casualty, losing his job as a result of cost-cutting at Kenilworth Road. The 50-year-old left the Sky Bet Championship strugglers via mutual agreement, with the club needing to reduce costs during the shutdown. A statement read: "Given the current circumstances affecting not only football but the world as whole, the club are taking an early move to restructure in order to reduce its cost base and to create efficiencies within the football department. As a result of amicable discussions, Graeme and the board of directors have agreed terms upon which he will leave his role with immediate effect."
Alan Pardew
Alan Pardew left his role as ADO Den Haag manager by mutual consent on Tuesday after the Dutch Eredivisie club maintained their top-flight status. Den Haag were seven points adrift of safety and almost certain to be in the relegation play-offs before the campaign was ended due to coronavirus last week. The Dutch FA did not enforce any relegation or promotion, meaning Den Haag stayed up, but Pardew and coaches Chris Powell and Paul Butler will not have their contracts renewed – they were set to expire on June 30.
