So just who is Avram Grant, who makes his debut as interim Chelsea manager in place of Jose Mourinho on Sunday against Manchester United?
Grant spent his career coaching in his native Israel until he came to England in June 2006 to take a front-office post as director of soccer at Portsmouth.
Chelsea owner Roman Abramovich, who is a friend of Grant's and once tried to take over Israeli club Hapoel Tel Aviv for the purpose of putting Grant in charge, then brought the 52-year-old Grant to Chelsea to serve as director of soccer in July.
Opinions on Grant in Israel, where he coached such clubs as Hapoel Petah Tikva, Maccabi Tel Aviv and Maccabi Haifa and the national team, are mixed.
Former national coach Shlomo Scharf called Grant "an illusionist." Another Israeli coach Ran Ben-Shimon, praised Grant, telling an Israeli web site: "The fact that Avram Grant has become Chelsea coach is the same as Neil Armstrong's historic landing on the moon."
Steve Clarke, a former Chelsea player, will remain as the Blues' assistant manager.
Grant and Clarke are rumored to be acting as caretakers, though, until Abramovich can work a deal for another acquaintance, Dutch coach Guus Hiddink, to take charge as manager. Hiddink is currently Russia's national team coach.
