Former Italian international Roberto Di Matteo has been confirmed as Andre Villas Boas' assistant Coach at Chelsea.
Di Matteo is an ex-midfielder at Stamford Bridge where he won two FA Cups with the London club.
The former Lazio player has been out of the game since he was sacked as West Brom boss in February after leading them to promotion last season.
Di Matteo was capped 34 times by Italy during his career. He scored two goals for the Azzurri in games against Poland and Slovakia.
