Carlo Ancelotti becomes Chelsea's eighth non-British manager since Ruud Gullit started the foreign invasion in May 1996.
The 49-year-old (right) is the third Italian in the Stamford Bridge hot seat and follows two Dutchmen, plus managers from Portugal, Israel and Brazil.
But Jose Mourinho and Guus Hiddink aside, the Blues' cosmopolitan bosses haven't fared always too well in England.
Sportsmail looks back on a managerial position that has often been lost in translation.
Ruud Gullit(May 1996 to February 1998)
The Dutchman was appointed player-manager of Chelsea in May 1996 when Glenn Hoddle left to manage England.
Gullit brought the FA Cup to Stamford Bridge in his first season courtesy of a 2-0 win over Middlesbrough, becoming the first non-British manager to win the famous trophy.
After guiding Chelsea to sixth in the Premier League in 1996-97, Gullit was sacked in February 1998. The Blues were second in the League and in the quarter-finals of two cup competitions.
