As it stands, Man City look to have the Premier League title in their grasp - 11 points ahead of nearest challengers Man Utd - and given the level of expectation and investment from title rivals, it is not beyond the realm of possibility that there could be managerial casualties later on in the season.
Ronald Koeman has already been replaced by Sam Allardyce at Everton, with chairman Farhad Morishi disillusioned with the Toffees' form given their vast investment in the playing squad over the summer.
With that in mind, here are a few previously anointed "chosen one's" who failed to deliver what they were expected to.
1. Mark Hughes (Blackburn to Manchester City)
In his four years in charge of Blackburn Rovers, Mark Hughes led the club to two FA Cup semi-finals, a League Cup semi-final and the UEFA Cup Round of 32. It was perhaps little surprise then when Manchester City , came calling in the summer of 2008 after the Welshman guided Rovers to a seventh place finish in the Premier League.
The final day of that summer's transfer window saw City pull off a then record transfer deal by a British club for Brazilian sensation Robinho for £32.5m following the club's takeover by the Abu Dhabi Group the same day.
Despite the now notorious financial backing enjoyed by City, Hughes could guide the club to tenth in his only full season at the club in 08/09, and a 4-3 victory at home to Sunderland in December 2009 wasn't enough to save Hughes his job as he was sacked with City sixth in the Premier League following a run of just two wins in eleven games.
Hughes has never returned to a Premier League contender, instead having spells at Fulham and QPR before joining current club Stoke in 2013.
2. Roy Hodgson (Fulham to Liverpool)
Another manager called upon to make the step up following an unexpected success with a supposed smaller club, Roy Hodgson's 2009/10 season saw him voted Manager of the Year after guiding Fulham to the UEFA Cup final, leading Liverpool to swoop for Hodgson as a replacement for long time manager Rafael Benitez.
Hodgson again did a job where he could on the continent, as Liverpool finished top of their Europa League group despite winning just two of their six group games. Hodgson however, would be gone before the knockout stages began.
The domestic campaign had been a different story for Hodgson's Liverpool side. They had been knocked out of the League Cup by League Two strugglers Northampton Town at Anfield on penalties, and when Hodgson was sacked in the aftermath of a 3-1 defeat at former club Blackburn Rovers in January 2011, the club were twelfth in the Premier League, with just six wins from twenty games.
Hodgson then spent just over a year at West Brom before a four spell as England manager saw catastrophic exits from both the 2014 World Cup and the 2016 European Championships, with Hodgson now in charge of Premier League basement dwellers Crystal Palace.
3. Brendan Rodgers (Swansea to Liverpool)
Little over a year after Hodgson's departure, Liverpool once again elected to go done the route of manager responsible for a smaller club's success, and this time it was Swansea City's Brendan Rodgers they decided to move for.
In two season's at the Welsh club, Rodgers guided the Swans to the Premier League for the first time before seeing them to a comfortable and impressive eleventh place finish in their debut 2011/12 season.
Rodgers subsequently made the move to Anfield, but after an infamous end to the 2013/14 season that was headlined by Steven Gerrard's slip to help Chelsea to victory at Anfield and the collapse of 3-0 lead to draw 3-3 with Crystal Palace saw Rodgers' side hand the Premier League title to Manchester City, the Northern Irishman became the first Liverpool manager to fail to win a trophy in his first three season's at the club.
Rodgers' fourth season at Liverpool, in 2015/16, was a short one. He was sacked just an hour after a 1-1 draw in the Merseyside Derby at Everton following a run of one win in nine games. Rodgers did however bounce back quickly north of the border, as he completed an unbeaten domestic campaign with Scottish giants Celtic the following season.
4. David Moyes (Everton to Manchester United)
Replacing Sir Alex Ferguson as manager of Manchester United was always going to be one of the toughest jobs in football, but even Ferguson believed that in David Moyes, United had found themselves the right man for the job.
Before Ferguson had even completed his final season in the Old Trafford dugout, United had announced that Moyes would leave Everton to take over from his fellow Scotsman on a six year contract. He lasted just over nine months.
After dropping out of the top four following a 1-0 defeat at Anfield on matchday three, United never returned to the Champions League spots, and suffered back to back home defeats for the first time since 1972 after 1-0 losses to Everton and Newcastle at Old Trafford.
It was Moyes' former club Everton who would go on to put the final nail in his United coffin with a comfortable 2-0 victory at Goodison Park in April 2014 spelling the end of Moyes' reign. The Scot is now manager of West Ham, following a brief spell in Spain with Real Sociedad and his resignation from Sunderland in the aftermath of their relegation from the Premier League in May 2017.
5. Roberto Martinez (Wigan to Everton)
After Moyes' departure, Everton themselves turned to a manager who had built his reputation through the divisions. Having taken Swansea from League One to the Championship, Martinez kept Wigan Athletic in the Premier League for three season's and taking an unforgettable F.A. Cup victory with them when they eventually did suffer relegation.
Martinez then went onto to make the move to Everton, where, despite that impressive first season in 2013/14 that saw the Toffees finish fifth, the club was unable to build upon Martinez's promising debut season.
The subsequent year saw Everton finish eleventh with early exits from both domestic cup competitions and a run to Round of 16 in the Europa League. Runs to semi-finals of both domestic cups the following year were not enough to paper over the cracks of another mid-table year in 2015/16, and Martinez was sacked following a 3-0 defeat at Sunderland in the penultimate game of the season.
September 2016 saw the Spaniard appointed as manager of Belgium's national side, and under Martinez the Red Devils secured qualification for a second consecutive World Cup twelve months later.
6. Paul Lambert (Norwich to Aston Villa)
After stunning the Football League by guiding Norwich City to back to back promotions as the Canaries went from League One to the Premier League in just two seasons between 2009 and 2011, Paul Lambert then oversaw a final day 2-0 win over Aston Villa to ensure Norwich ended their first season back in the top flight in twelfth in 2011/12.
By the time the 2012/13 season began, Lambert was in charge of Aston Villa. In two-and-a-half years in charge of the Midlands side, Lambert was never really able to fully galvanise his side. Each of Lambert's two fulls seasons in charge ended with the Villa Park side fifteenth in the Premier League having flirted with relegation on both occasions.
Lambert was not so lucky the third time round however, and a 2-0 defeat at Hull in February 2015 saw the Scotsman sacked with Villa eighteenth in the League 25 league games into Lambert's third season with the club. Lambert then spent each of the next two seasons at Blackburn and Wolves respectively, finishing fifteenth on The Championship both times.
