The Daily Mail says the Italian's assistant Bruno Demichelis is expected to follow the manager, which could spell the end of his Mind Room, the psychology unit at the training ground.
So is fitness coach Giovanni Mauri and Italian opposition scouts Luigi La Sala and Giorgio Ciaschini. Sporting director Frank Arnesen is bound for Hamburg.
He is taking several scouts with him from Stamford Bridge and has shown an interest in signing some of the club's young players including Jeffrey Bruma and Patrick van Aanholt, who signed a new four-year deal at Chelsea yesterday.
Senior players are expected to leave too, including Nicolas Anelka, Jose Bosingwa and Florent Malouda, all of which clears the decks for Abramovich to start his biggest restructuring programme since he bought the club in 2003, with significant changes to the coaching, scouting and academy departments.
