Chelsea goalkeeper Petr Cech will welcome his former Rennes coach Christophe Lollichon to Stamford Bridge this week.
Lollichon is leaving his position as Rennes goalkeeper coach to take up a similar role at Chelsea and to again work with Czech Republic international Cech.
Lollichon was with Rennes since 1999 and joins Chelsea on a two-and-a-half year deal. He will be replaced at Rennes by former Monaco goalkeeper Andre Amitrano.
