LONDON (AP) -A look at the eight Chelsea managers that have served under Russian owner Roman Abramovich:
Ranieri was the first manager to be fired by Abramovich. The Italian, who became known as the "Tinkerman" because of his tendency to fiddle with his team, was hired in September 2000 by previous Chelsea owner Ken Bates. He was fired in May 2004 despite guiding Chelsea to second place behind Arsenal and reaching the Champions League semifinals.
Mourinho came to Chelsea after winning the Champions League title with FC Porto in 2004. Upon arrival, he called himself the "Special One," and then justified the name, becoming the most successful Chelsea manager ever. In three years, he won back-to-back Premier League titles in 2004-05 and 2005-06, the FA Cup in 2007 and two League Cups in 2005 and 2007.
A power struggle with the Russian owner paved the way for his exit in September 2007.
Grant didn't have the bravado and braggadocio of Mourinho. But despite reports that he didn't have control of the dressing room, he finished second in the league. He was also the first Chelsea manager to guide the team to the Champions League final, but the Blues lost to Premier League champion Manchester United on penalties.
He was fired in May 2008.
Luiz Felipe Scolari
A new season in August 2008 welcomed a new manager in Scolari, a Brazilian who led his home country to the 2002 World Cup title. But with Chelsea underperforming and control in the dressing room once again proving to be a problem, Abramovich lost his patience after only seven months, firing Scolari in February 2009.
Hiddink temporarily took charge of Chelsea in February 2009 while keeping his job as coach of Russia's national team. The Dutch veteran lost only one game as the team finished third in the Premier League and reached the Champions League semifinals.
Hiddink left at the end of the season to resume his international job.
Ancelotti became the fifth man to manage the club in less than two years in June 2009. The Italian was a two-time Champions League winner as coach of AC Milan, and won the Premier League and FA Cup double in his first Premier League season.
It was under Ancelotti that Chelsea paid 50 million pounds ($80 million) for Liverpool striker Fernando Torres. But his second season was less successful, as Chelsea finished second, nine points behind Manchester United, and Ancelotti lost his job in May 2011.
Villas-Boas started last season as Chelsea's new manager. The suave Portuguese, a former Porto coach who won the Europa League title in 2011, shared many similarities with Jose Mourinho. But he didn't live up to the same success. The club dropped out the top four, and his controversial selection decisions got him fired by March.
Roberto Di Matteo
Di Matteo was appointed caretaker-manager following Villas-Boas' departure at the end of last season. The Blues finished in sixth place in the Premier League, but Di Matteo finally gave Abramovich the European glory he had been craving.
After beating Liverpool in the FA Cup final, Chelsea went on to beat Bayern Munich on penalties in the Champions League final.
Chelsea added a number of high-profile players to the squad in the offseason, including Oscar and Eden Hazard, but Di Matteo was fired Wednesday after a run of eight games in all competitions with only one win.
