Following the success of last season's reserve side coach Steve Holland steps up to work with the senior squad, becoming an assistant first team coach.
Christophe joined Chelsea in November 2007 from Rennes, where he had previously worked with Petr Cech.
He had been at the French club since 1999, in which time he has taken care of a host of top class goalkeepers. As well as cech, he mentored French international Michaël Landreau, Andreas Isaksson, Christophe Revault and Patrice Luzi, formerly of Liverpool.
His time there has coincided with the club's best ever period, regularly battling for European football at the top end of the French league. When he joined the club, he began working in the Academy, but quickly rose up the ladder to work with the first team, where he met a young Cech during the 2003/4 season.
Much like Avram Grant, Christophe never played at the top level, although as a youth, he would train once a week with Nantes, where he occasionally got to share a training pitch with future Chelsea players Marcel Desailly and Didier Deschamps.
Realising that his path in football lay with coaching, at the age of 24, he gave up the amateur game and became a coach with Ancenis near Nantes.
His role there was to build an academy, and he eventually achieved success that led to Rennes offering him a post.
Goalkeeping has long been his love, choosing the position as a child because of the individuality of the strip, and the ability to use hands as well as feet.
Christophe is renowned in his homeland for his qualities of hard work, attention to detail and communication, and all at Chelsea welcome him to his new role.
The post of goalkeeper coach became available after Silvino Louro left the club with José Mourinho.
At the start of the 2005/6 season, Mick moved up to work with the first team squad after ten years in charge of the reserves.
His first Chelsea job was in 1990 - nine months looking after the youth team having previously coached West Ham's first team.
He moved on to coach and then manage Ipswich before returning to Chelsea and his long spell of service with our second string.
As a player, Newcastle-born Mick played with Sunderland and West Ham, the latter signing him to replace England's World Cup winning captain Bobby Moore.
As a Chelsea coach, he has played his part in developing the current England captain, as well as many other youngsters who have grown into first team players throughout the divisions.
