Abramovich is in his 18th year since he bought the English side but has already appointed 15 head coaches during that period.
The Russian has transformed Chelsea to one of the biggest clubs in the world since he took over the club at the beginning of this century.
Chelsea have seen enormous success under the tutelage of Abramovich but the 54-year-old has always been criticized for his hire-and-fire policy.
Abramovich’s most recent sacking sparked outrage amongst Chelsea faithful, with club legend Frank Lampard losing his job as head coach.
Just like previous times, Abramovich has been vindicated as Chelsea have been in good form since the appointment of Thomas Tuchel.
The owner said Chelsea's culture is “definitely focused on performance, it is at the same time supportive, inclusive and diverse. Both elements are critical to our success and one does not work without the other.”
“I think we are pragmatic in our choices. And we are comfortable making the right changes at the right time to ensure we can achieve our long-term ambitions.
"I hope it also says something about the clarity of the long-term ambition of the club. Those who join understand the objectives both on the pitch, as well as the wider positive role the club plays in the community.”
Chelsea have won 16 major trophies which includes five Premier Leagues, one Champions League, two Europa Leagues and five FA Cups under Abramovich.
