Sam Allardyce has maintained his remarkable record of never having been relegated from the top flight after Crystal Palace secured their place in the Premier League for next season.
The 62-year-old earned promotion with Bolton in 2001 and kept them up six times, and has since steered Blackburn, West Ham and Palace to safety.
Here, Press Association Sport looks at some of Allardyce's most impressive escapology acts.
BOLTON 2001-02
Allardyce kept faith with the players who had overcome Preston in the play-off final. Three wins from their first three games got Wanderers up and running, but a run of 12 games without a win either side of Christmas left them in trouble. Allardyce responded by bringing in French World Cup winner Youri Djorkaeff, who scored in crucial victories against Charlton and Ipswich to help Bolton finish 16th.
BOLTON 2002-03
Despite the arrival of Nigeria star Jay-Jay Okocha to add some flair - and long throw-ins - second-season syndrome kicked in at the Reebok as they lost seven of their first 11 games. However, late goals from Djorkaeff and Delroy Facey provided a 4-2 victory over Birmingham which acted as a catalyst for Bolton to win six and draw five of their last 13 games and condemned West Ham to the drop instead.
BLACKBURN 2008-09
After a brief stint with Newcastle, Allardyce returned to management with Blackburn when Paul Ince was sacked with the club 19th in the league after 17 games - the last five of which had all been lost. Allardyce kicked off his reign with a 3-0 win against Stoke and El Hadji Diouf proved to be a shrewd signing as Rovers lost only once at Ewood Park in the second half of the season.
SUNDERLAND 2015-16
After the relative mid-table comfort of his West Ham tenure, Allardyce returned to fire fighting by replacing Dick Advocaat at Sunderland, with the Black Cats having taken three points from eight games. A 3-0 win over rivals Newcastle kick-started the survival bid, and victories by the same margin over Norwich and Everton during the run-in secured their top-flight status.
CRYSTAL PALACE 2016-17
Allardyce succeeded Alan Pardew with the Eagles 17th in the Premier League - although things got worse before they got better. The former England boss had to wait seven league games for his first win, but surprise victories at Chelsea and Liverpool - either side of thumping Arsenal 3-0 at Selhurst Park - and a 4-0 hammering of Hull, who dropped out of the Premier League as a result, ensured Palace retained their place in the top tier.
