Sam Allardyce's timeline
Sam Allardyce is back in football management with Everton.
The 63-year-old has been appointed Toffees boss on an 18-month deal six months after leaving his last post with Crystal Palace.
Here, Press Association Sport takes a look back at Allardyce's recent highs and lows .
OCTOBER 2015: Allardyce is appointed manager of Sunderland, who sit 19th in the Premier League, with just three points from their first eight games of the season. He sees the club beat Newcastle 3-0 at the Stadium of Light in his second match in charge.
DECEMBER 2015: Five successive defeats put Sunderland in the relegation zone with 12 points after 19 matches.
APRIL 2016: Sunderland give their survival chances a boost with a 3-0 win at fellow relegation battlers Norwich, which is followed by draws against both Arsenal and Stoke.
MAY 2016: Sunderland come from behind to beat Chelsea 3-2 at the Stadium of Light, which leaves them a point above 18th-placed Newcastle with a game in hand. Everton are then defeated 3-0 to secure their top-flight status and send the Magpies down.
JULY 2016: Following England's exit from the European Championships with defeat against Iceland, the Football Association agrees a compensation deal with Sunderland to appoint Allardyce on a two-year deal after Roy Hodgson's decision to stand down.
SEPTEMBER 2016: Allardyce's England reign gets off to a winning start in a World Cup qualifier away to Slovakia with a late goal from Adam Lallana . It proves to be his one and only match as England manager as Allardyce resigns following just 67 days in the post after the Daily Telegraph releases secretly-filmed footage of him making controversial remarks about a variety of subjects, including side work and circumventing FA regulations.
DECEMBER 2016: Following the departure of Alan Pardew, Allardyce is appointed as the new manager of Crystal Palace on a two-and-a-half-year contract, with the Eagles just a point above the drop zone.
JANUARY 2017: Palace win their first match under Allardyce against his former club Bolton in the FA Cup. A first Premier League victory follows at Bournemouth on January 31.
APRIL 2017: The resurgent Eagles make it four wins in a row after they beat title leaders Chelsea 2-1 at Stamford Bridge to sit 16th and four points clear of the bottom three. After defeat at Southampton, Allardyce's men go on to defeat Arsenal and Liverpool.
MAY 14, 2017: Palace secure their place in the Premier League with a 4-0 victory over Hull, who are relegated to the Championship as a result. They end the season with a 2-0 defeat at Manchester United but in 14th place, seven points clear of the relegation zone.
MAY 23, 2017: Allardyce unexpectedly announces his departure from Palace - five months to the day since his appointment - saying he has "no ambitions" to take another job.
NOVEMBER 29, 2017: After appearing to rule himself out of the job, Everton's failed pursuit of Watford boss Marco Silva sees them return to Allardyce, who agrees to take over at Goodison Park.
