Football management can be an unforgiving profession even for the best in the business, as these bosses found out...
DAVID MOYES: MANCHESTER UNITED
It was always going to be difficult taking over from Sir Alex Ferguson, but Manchester United fans were relatively upbeat with the appointment of his compatriot, David Moyes, in 2013. Moyes previously enjoyed 11 successful years at Everton.

10 months later, he was sacked with the then reigning champions seventh in the Premier League and out of the hunt for silverware.
Last season, new manager Louis van Gaal led Red Devils back into the Champions League.

Moyes, meanwhile, guided Real Sociedad to 12th place in La Liga.
ROY HODGSON: LIVERPOOL
The current England manager had just been named LMA manager of the year after guiding Fulham to the 2009/10 Europa League final when he took over from Rafael Benitez at Liverpool.
In January 2011, he was replaced by Kenny Dalglish, having only won seven of his 20 league games at the club.
Liverpool have only won one trophy - the 2011/12 League Cup - since; but pushed 2013/14 Premier League winners Manchester City to the final day of the season.
Hodgson had an impressive stint at West Bromwich Albion before taking the England job, which he remains in despite group stage elimination from last year's World Cup. England have since won all six of their Euro 2016 qualifiers.
RAFAEL BENITEZ: INTER MILAN
Hodgson's predecessor did not fare much better at his next club, then reigning Italian and European champions Inter Milan, and was sacked in December 2010 with the club seventh in Serie A.
Although eventually earning Champions League qualification, Inter have not won a league title since. Last season, they finished eighth.
Benitez won the 2012/13 Europa League at Chelsea and the following season's Coppa Italia with Napoli, before recently joining Real Madrid.
ANDRÉ VILLAS-BOAS: CHELSEA
André Villas-Boas arrived at Chelsea after winning the league, cup and Europa League treble with FC Porto in 2010/11.
Despite having been viewed as an heir to José Mourinho; Villas-Boas was sacked in March 2012 with Chelsea fifth in the Premier League and on the verge of Champions League elimination.
Roberto Di Matteo then guided Chelsea to European and FA Cup glory and they continued to win silverware under Benitez and, more recently, Mourinho - who has returned to the club.
Villas-Boas managed Tottenham Hotspur for a year and a half, before joining Zenit St. Petersburg and winning the Russian league.
BRIAN CLOUGH: LEEDS UNITED
Regarded by many as the greatest British manager ever, Clough was a surprise appointment at Leeds United - whom he had previously criticised for their physical style of play - in 1974.
He was sacked within 44 days, having won one of his six league games.
Leeds went on to make the European Cup final.
Unfortunately for the Yorkshire club, they have only won one league title since and finished 15th in last season's Football League Championship.
Clough, meanwhile, won a league title and two European Cups with Nottingham Forest.
