From TheChels.info - The Chelsea Football Club Wiki
Paul Clement (born in Reading, England) was formerly a First Team Coach at Chelsea, having fulfilled several other roles in two spells at the club, from 1995 until 2000, and from 2006 until 2011. He is the older brother of former Blues academy product Neil Clement. Clement first worked with the first team under Guus Hiddink, a position that was made permanent while Carlo Ancelotti was manager. He would later assist Ancelotti at Paris Saint-Germain and Real Madrid.
First Chelsea spell and Fulham
Paul had no playing career to speak of and instead went into coaching at an early age. In 1995 he joined Chelsea's academy coaching ranks, working with the younger age groups as they began their footballing development. He spent five years at the club before moving to Fulham, where he would coach their Under-16 team. At the same time, he adopted the Assistant Manager role for the Republic of Ireland's Under-21 team, working under Don Givens.
Second Chelsea spell
In 2006, Paul was to return to Chelsea to coach their Under-16 team. When Ruud Kaiser left at the end of the 2006-07 season, Paul was promoted to Youth Team Manager, which allowed him to continue working with the same group of players he had been coaching at Under-16 level as they graduated to scholarship level. In his first season at Under-18 level, Clement led the Blues to the FA Youth Cup Final, but they were unable to beat Manchester City over two legs.
Nonetheless, his reputation was growing around the club and in December 2008 he was promoted to Reserve Team Manager on a full-time basis, having taken the reigns after Brendan Rodgers left to join Watford. In February 2009, Paul began working with the first team squad when Guus Hiddink replaced Luiz Felipe Scolari and would eventually relinquish the Reserve Team reigns to Steve Holland in August 2009, when his position among Carlo Ancelotti's first team backroom staff was made permanent. Clement left the club following the arrival of André Villas-Boas in June 2011.
After a short spell as Steve Kean's assistant at Blackburn, Clement once again joined up with Ancelotti as part of his staff at Paris Saint-Germain. When the former Chelsea manager was hired by Real Madrid in 2013 he took Clement with him to the Estadio Santiago Bernabéu.
