Blues owner Roman Abramovich is infamous for his impatience with his managers – so how have coaches under his reign fared compared to each other?

Chelsea have gone through more managers than Zlatan Ibrahimovic goes through clubs, and Maurizio Sarri's position is now in jeopardy following his side's 6-0 thumping by Man City.

But how have Chelsea's many, many bosses performed under the 16-year reign of Abramovich? Goal takes a look.

Accomplishments: None

Reason for dismissal: Finishing in second place with no silverware.

Having already forged a close friendship with Abramovich, Grant was first appointed Director of Football at Chelsea before replacing Mourinho as head coach in 2007. At the time of his managerial appointment, he did not hold the required top-flight coaching certification from UEFA and was unpopular with the fans – as they had been protesting Mourinho's departure.

Grant led Chelsea to the League Cup final and the Champions League final but lost both, with captain John Terry slipping before taking his penalty in the shootout. Had he scored, Chelsea would have won. Grant was relieved of his duties at he end of the season despite leading Chelsea to a second-placed Premier League finish.

Accomplishments: None

Reason for dismissal: Deteriorating and disappointing league form.

The Brazilian took over as manager from Avram Grant in the summer of 2008 but only lasted eight months. Defeat to Liverpool was the final straw for the Chelsea hierarchy following deteroriating performances in the league, and was replaced by Hiddink.

Accomplishments: Premier League (2009-10), FA Cup (2009-10), Community Shield (2009)

Reason for dismissal: Finishing in second place with no silverware.

Poor Ancelotti was sacked on the bus back to London following a 1-0 defeat away at Everton towards the end of his second season in charge.

In his debut season with the Blues, Ancelotti won the double – the league and the FA Cup – but his failure to repeat his success in his second year led to his harsh dismissal before the season even ended.

Ancelotti was let go from the Blues sporting a record of 67 wins, 20 draws and 22 losses in 109 matches (in all competitions). His win-rate at Chelsea is the third-highest in Premier League history, after Mourinho and Sir Alex Ferguson.

Getty4Andre Villas-Boas (2011-12)

Accomplishments: None

Reason for dismissal: Poor form and falling out with several key players as well as Abramovich, and was criticised for his team selection and his tactical choices.

Chelsea paid Porto a world record of €15m to appoint Villas-Boas as manager, and his reign started off strongly, winning the 2011 Barclays Asia Trophy. His Premier League form was decent, though pressure started to mount on Villas-Boas in February when his side dropped out of the top four after defeat to Everton.

Villas Boas' team selection and tactics were questioned by Abramovich as well as the club's technical director, and his decision to leave Frank Lampard, Michael Essien and Ashley Cole on the bench during a Champions League game garnered criticism. The Portuguese coach was then relieved of his duties following a 1-0 league defeat to West Brom in March, and replaced by Di Matteo.
