'You're Fired': Why Every Chelsea Manager During the Roman Abramovich Era Was Sacked

Since Roman Abramovich bought the club in 2003, Chelsea have appeared to operate a revolving-door policy when it comes to managers.

Short term success has often been prioritised, with managers finding themselves out of a job after a few poor results. Whilst Antonio Conte is currently still in charge at Chelsea, reports linking Napoli's Maurizio Sarri to the London club are persistent, as are the signs that neither Chelsea or Conte want to continue their professional relationship.

But what is Sarri (potentially) getting himself into? What does he need to do to break the trend of short term managers at Stamford Bridge? Here, we take a look at the reasons why each manager under Abramovich lost his job.

Note: This list only includes managers who were at the helm for a substantial period of time, so Ray Wilkins's six days in charge in 2009 will not be mentioned, nor will Steve Holland's two-day reign in 2015.

1. Claudio Ranieri: September 2000 - May 2004

Ranieri was the man in charge when Abramovich bought the club in 2003. Abramovich invested heavily in the club in his first season, spending over £120m on the likes of Damien Duff, Claude Makelele and Hernan Crespo.

However, days after he bought the club, Abramovich was spotted meeting with Sven-Goran Eriksson, and rumours about Eriksson's arrival at Stamford Bridge haunted Ranieri for his final season at the club. Abramovich was clearly looking to replace Ranieri with a manager who could guide Chelsea to greatness.

Despite their huge signings, Chelsea finished second in the Premier League, and Ranieri lost all hope of keeping his job as his side were beaten by Monaco in a Champions League semi final which saw Ranieri utilise strange substitutions and tactics. The "tinkering" which he would become famous for with Leicester City was a big reason for his downfall at Chelsea.

Eriksson signed a new deal with England, and the emergence of a special Portuguese manager meant Ranieri was finally dismissed at the end of the season.

2. Jose Mourinho: June 2004 - September 2007

After guiding Porto to an unlikely Champions League triumph, Mourinho was quickly earmarked as the man to lead Chelsea for the future, and a deal was quickly finalised. He continued his managerial excellence by delivering countless trophies to Chelsea, including back-to-back Premier League titles in his first two seasons.

During the 2006-07 season, rumours of Mourinho's departure refused to subside. Mourinho began to clash with Abramovich, sporting director Frank Arnesen and Piet de Visser, a close personal adviser to Abramovich. Mourinho became frustrated as he believed Abramovich was undermining him by forcing Mourinho to play certain players or use certain tactics.

Abramovich had been targeting AC Milan striker Andriy Shevchenko for years, and finally completed a deal for the Ukranian in 2006. However, Mourinho did not want Shevchenko at the club and preferred Didier Drogba. Abramovich insisted that Shevchenko was played, despite clearly struggling. He also hired Avram Grant as a director of football, despite Mourinho's clear disapproval of the idea.

Mourinho's Chelsea finished second in the 2006-07 season, but endured a tough start to the following season. A loss to Aston Villa was followed by draws with Blackburn Rovers and Rosenborg, before Mourinho shockingly left the club. Whilst this looked to be a sudden decision, Mourinho's relationship with the board had become toxic, and he subsequently left the club.

3. Avram Grant: September 2007 - May 2008

Grant's presence at the club had been a big factor in Mourinho's departure, and fans were unhappy that their beloved Mourinho had been forced out of the club. Grant did not even hold the required qualifications to be Chelsea manager when he was hired.

Players also felt that Grant was not good enough to manage Chelsea, with The Guardian reporting that unnamed Chelsea players felt Grant was "25 years behind the times".

Grant's lone season in charge could have been completely different. He did not lose a home game and guided Chelsea to a second place finish in the Premier League, whilst the team were also beaten finalists in both the League Cup and the Champions League. Should he have won these matches, Grant may have survived as Chelsea manager.

Ultimately, his lack of popularity amongst the fans and players was a huge reason behind Grant's dismissal.

4. Luiz Felipe Scolari: July 2008 - February 2009

Scolari left his position as manager of Portugal to join Chelsea, openly admitting that the financial side of the deal was a huge factor for his decision. He took the league by storm when he arrived, implementing new tactics to guide Chelsea to the top of the league.

However, once results started deteriorating, so did almost everything else. Firstly, Scolari's English was very basic, and players became frustrated that he was not making enough effort to communicate with them. He also stopped attending press conferences and fans viewed this as a lack of respect towards the club. 

His tactics were questioned by both fans and players, with his refusal to utilise two strikers meaning Didier Drogba and Nicolas Anelka were often used as wingers. Draws and losses to smaller sides saw the players openly question his tactics, whilst fans were also heard chanting about their frustrations during matches.

Chelsea lost their phenomenal home record under Scolari, and it appeared as though nobody was happy at the club. A string of poor form saw Scolari replaced, meaning the Brazilian failed to complete a whole season with Chelsea.

5. Guus Hiddink: February 2009 - May 2009

Hiddink was brought in on a temporary basis whilst he was still manager of the Russian national team, and constantly stated that he was not interested in taking the job permanently as he already had a contract with Russia.

Hiddink and Scolari were polar opposites. The Dutchman rejuvenated Chelsea with his positive attitude and tactics, and results were immediate, as the team began dominating once more, but unfortunately for Chelsea, the damage of Scolari's reign meant Hiddink was mathematically unable to win the league.

He took Chelsea to the Champions League semi final, which saw them beaten by Barcelona after a controversial refereeing performance. His final game saw him lift the FA Cup, and fans and players both cried for Hiddink to take the job permanently, but Hiddink's loyalty to Russia was unwavering. Players bought him a watch and a signed Chelsea shirt as a token of their gratitude. Hiddink's time as manager was arguably the most positive ever seen at Chelsea.

6. Carlo Ancelotti: June 2009 - May 2011

With Hiddink returning to Russia, Chelsea opted to hire Carlo Ancelotti in 2009. The Italian enjoyed a generally successful time in London, and has the third highest win percentage in Premier League history, behind Jose Mourinho and Sir Alex Ferguson.

However, like so many before and after him, things unravelled very quickly. Ancelotti's assistant manager, Ray Wilkins, was surprisingly dismissed in November 2010, changing the atmosphere at Stamford Bridge dramatically. Results on the pitch quickly plummeted, including a particularly humiliating 3-0 defeat to Sunderland.

His side began playing very uninspiring football, with Yossi Benayoun one of the few creative players in the side. The £50m signing of Fernando Torres was also a point of controversy in the club, as Abramovich forced Ancelotti to persevere with the expensive Torres, despite the Spaniard's well-documented struggles.

Ancelotti's final season was the least successful since Abramovich bought the club, and he was unceremoniously dismissed in a corridor at the end of the season, putting an end to the negative atmosphere at Stamford Bridge.

7. Andre Villas-Boas: June 2011 - March 2012

A young Portuguese manager who had achieved success with Porto; where have we heard that one before?

Villas-Boas joined Chelsea as one of the most exciting managers in world football, after Chelsea paid an astounding £13m to release him from Porto. At 33 years old, he was meant to be the man to bring inspiring football to Stamford Bridge for the foreseeable future.

However, after a positive pre-season, Chelsea never got going in the Premier League. His side were very disappointing and were quickly outside the top four. He cancelled relaxation days for his players and instead criticised them, leading several senior players to voice their displeasure with Villas-Boas.

The young manager often dropped some of Chelsea's older, and better, players, including during a 3-1 loss to Napoli in the Champions League as Frank Lampard and Ashley Cole were forced to watch from the bench. The board at Chelsea questioned Villas-Boas's tactics after this game, and he was relieved from his duties soon after. 

His relationship with both the players and the staff at Stamford Bridge, coupled with his disappointing results, meant Villas-Boas was quickly shown the exit door.

8. Roberto Di Matteo: March 2012 - November 2012

Di Matteo, assistant to Villas-Boas, was initially brought in as a caretaker manager, but FA Cup and Champions League triumphs saw Di Matteo offered a two-year contract at Stamford Bridge.

Results were initially positive for Di Matteo but, once again, things suddenly soured. Results in the league dried up, and a 3-0 defeat to Juventus had Chelsea on the brink of exiting the Champions League at the group stage. Rumours emerged that the Italian had effectively given the managerial duties to senior players in the team, so when results dried up, it appeared as though there was nobody who knew how to turn things around. 

Di Matteo simply did not show any sign of changing tactics or improving results, and the Champions League humiliation proved to be too much for Abramovich, and Di Matteo was swiftly replaced. After winning two major trophies in eight months, the decision to fire Di Matteo was one of the more controversial sackings in Chelsea history.

9. Rafa Benitez: November 2012 - May 2013

Unveiled as Di Matteo's temporary replacement on the same day as the Italian was dismissed, the environment only soured around Stamford Bridge. During his time as Liverpool manager, Benitez had made some unsavoury comments about Chelsea, and fans of Chelsea proved that they had long memories.

Benitez received a toxic reception during his first game and throughout the majority of his reign. He even criticised the club for giving him the title of 'interim manager' and attacked the fans for their displays of frustration, confirming he would leave the club at the end of the season after an FA Cup match against Middlesbrough saw a particularly vocal crowd vent their frustration towards Benitez.

Results were mixed, although Chelsea dropped a further 12 points behind Manchester United during Benitez's time in charge. Despite this, he guided the team to third place in the league, and managed to win the Europa League. Whether he was ever intended to be a long-term manager for Chelsea or not is irrelevant, as the fans ensured that Benitez was not keen on sticking around.

10. Jose Mourinho: June 2013 - December 2015

Fans could not have been happier to see Mourinho return to Chelsea, as he was still heralded as a hero at Chelsea. He found success with Chelsea in the 2014-15 season, winning the Premier League as his side lost just three games all season.

Unfortunately, the 2015-16 could have hardly got off to a worse start. A 2-2 draw with Swansea was hugely controversial after a clash between Mourinho and physio Eva Carneiro, which sparked a lengthy legal battle between Carneiro and the club.

Chelsea's form continued in miserable fashion, as the club found themselves around the relegation zone. His tactics became exposed and his comments to the media came across as a man who simply refused to acknowledge the gravity of the situation, including referring to a 3-0 demolition by Manchester City as a 'fake' result.

Press conferences brought out a frustrated side to Mourinho that had hardly been seen before. He appeared to blame everybody apart from himself, even criticising Chelsea fans for their inability to help the team. He turned on his own players, who in turn appeared uninterested for the majority of the season. After losing nine out of 16 league games, Mourinho was finally let go again.

11. Guus Hiddink: December 2015 - May 2016

With the mood at Stamford Bridge at an all time low, there was only one man who could save the club - Guus Hiddink. The Dutchman's optimism was much-needed, as the club found themselves in 16th place upon his arrival.

He immediately embarked on a run of 12 matches without defeat, setting a Premier League record for a new manager. Hiddink, however, is not a miracle worker. The atmosphere around Stamford Bridge was so negative, that several players seemed desperate to finish the campaign and start again. 

Results were mixed, but Hiddink managed to drag Chelsea to the top half of the Premier League, but could not help Chelsea qualify for European football. Chelsea had already began looking for a long-term solution, settling on Italy manager Antonio Conte, who took over once the season had ended.
